Prepare to conquer your understanding of this crucial chemical concept!
Understanding the Basics: What is Covalent Bonding?
Covalent bonding is a type of chemical bond where atoms share electrons to achieve a more stable electron configuration. Unlike ionic bonding, where electrons are transferred, in covalent bonding, atoms essentially "pool" their electrons to complete their outermost electron shells (also known as valence shells). This sharing creates a strong attraction between the atoms, holding them together to form molecules. Think of it like two people sharing a single resource – both benefit from the shared resource, making them stronger together.
The Octet Rule and Covalent Bonding
The driving force behind covalent bonding is the octet rule. This rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their valence shell, achieving a stable, noble gas configuration. Hydrogen is an exception, aiming for a duet (two electrons) in its valence shell. Atoms achieve this stability by sharing electrons with other atoms, forming covalent bonds.
Types of Covalent Bonds: Exploring the Variations
Covalent bonds aren't all created equal. Several factors influence their characteristics, leading to variations in bond strength and properties.
Nonpolar Covalent Bonds: Equal Sharing
In nonpolar covalent bonds, electrons are shared equally between two atoms of similar electronegativity. Electronegativity refers to an atom's ability to attract electrons in a bond. When electronegativities are similar, neither atom exerts a stronger pull on the shared electrons, resulting in a balanced distribution. A classic example is the bond in a diatomic oxygen molecule (O₂).
Polar Covalent Bonds: Unequal Sharing
Polar covalent bonds involve the unequal sharing of electrons between atoms with different electronegativities. The atom with higher electronegativity attracts the shared electrons more strongly, creating a slightly negative charge (δ-) on that atom and a slightly positive charge (δ+) on the other atom. This creates a dipole moment, a measure of the separation of positive and negative charges within a molecule. Water (H₂O) is a prime example of a molecule with polar covalent bonds.
Coordinate Covalent Bonds: A Special Case
Coordinate covalent bonds, also known as dative bonds, are a specific type of covalent bond where both shared electrons originate from the same atom. One atom donates a lone pair of electrons to another atom that has an empty orbital. This is frequently seen in complex ions and some organic molecules.
Properties of Covalently Bonded Compounds
Covalent compounds exhibit unique properties that distinguish them from ionic compounds:
Lower melting and boiling points: Covalent bonds are generally weaker than ionic bonds, leading to lower melting and boiling points.
Poor electrical conductivity: Covalent compounds usually do not conduct electricity because they do not have free-flowing ions or electrons.
Often exist as gases, liquids, or low-melting solids: The weaker intermolecular forces in covalent compounds often result in lower melting and boiling points, leading to their existence in various states of matter at room temperature.
Solubility varies: The solubility of covalent compounds depends on the polarity of the molecule and the polarity of the solvent. Polar covalent compounds tend to dissolve in polar solvents, while nonpolar covalent compounds dissolve in nonpolar solvents.
Real-World Applications of Covalent Bonding
Covalent bonding is fundamental to the existence of countless molecules crucial to life and industry. From the DNA in our cells to the plastics in our everyday objects, covalent bonds are everywhere. Examples include:
Organic chemistry: The backbone of organic molecules, including hydrocarbons, carbohydrates, proteins, and nucleic acids, is formed through covalent bonds.
Polymer science: Synthetic polymers, such as plastics and rubbers, are formed through extensive covalent bonding.
Pharmaceuticals: Many drugs and medications are organic molecules held together by covalent bonds.

| chemthink covalent bonding: Students at Risk of School Failure José Jesús Gázquez, José Carlos Núñez, 2018-10-18 The main objective of this Research Topic is to determine the conditions that place students at risk of school failure, identifying student and context variables. In spite of the fact that there is currently little doubt about how one learns and how to teach, in some countries of the “developed world,” there is still there is a high rate of school failure. Although the term “school failure” is a very complex construct, insofar as its causes, consequences, and development, from the field of educational psychology, the construct “student engagement” has recently gained special interest in an attempt to deal with the serious problem of school failure. School engagement builds on the anatomy of the students’ involvement in school and describes their feelings, behaviors, and thoughts about their school experiences. So, engagement is an important component of students’ school experience, with a close relationship to achievement and school failure. Children who self-set academic goals, attend school regularly and on time, behave well in class, complete their homework, and study at home are likely to interact adequately with the school social and physical environments and perform well in school. In contrast, children who miss school are more likely to display disruptive behaviors in class, miss homework frequently, exhibit violent behaviors on the playground, fail subjects, be retained and, if the behaviors persist, quit school. Moreover, engagement should also be considered as an important school outcome, eliciting more or less supportive reactions from educators. For example, children who display school-engaged behaviors are likely to receive motivational and instructional support from their teachers. The opposite may also be true. But what makes student engage more or less? The relevant literature indicates that personal variables (e.g., sensory, motor, neurodevelopmental, cognitive, motivational, emotional, behavior problems, learning difficulties, addictions), social and/or cultural variables (e.g., negative family conditions, child abuse, cultural deprivation, ethnic conditions, immigration), or school variables (e.g., coexistence at school, bullying, cyberbullying) may concurrently hinder engagement, preventing the student from acquiring the learnings in the same conditions as the rest of the classmates. |

| chemthink covalent bonding: Introduction to Graph Neural Networks Zhiyuan Zhiyuan Liu, Jie Jie Zhou, 2022-05-31 Graphs are useful data structures in complex real-life applications such as modeling physical systems, learning molecular fingerprints, controlling traffic networks, and recommending friends in social networks. However, these tasks require dealing with non-Euclidean graph data that contains rich relational information between elements and cannot be well handled by traditional deep learning models (e.g., convolutional neural networks (CNNs) or recurrent neural networks (RNNs)). Nodes in graphs usually contain useful feature information that cannot be well addressed in most unsupervised representation learning methods (e.g., network embedding methods). Graph neural networks (GNNs) are proposed to combine the feature information and the graph structure to learn better representations on graphs via feature propagation and aggregation. Due to its convincing performance and high interpretability, GNN has recently become a widely applied graph analysis tool. This book provides a comprehensive introduction to the basic concepts, models, and applications of graph neural networks. It starts with the introduction of the vanilla GNN model. Then several variants of the vanilla model are introduced such as graph convolutional networks, graph recurrent networks, graph attention networks, graph residual networks, and several general frameworks. Variants for different graph types and advanced training methods are also included. As for the applications of GNNs, the book categorizes them into structural, non-structural, and other scenarios, and then it introduces several typical models on solving these tasks. Finally, the closing chapters provide GNN open resources and the outlook of several future directions. |

| chemthink covalent bonding: Graph Representation Learning William L. William L. Hamilton, 2022-06-01 Graph-structured data is ubiquitous throughout the natural and social sciences, from telecommunication networks to quantum chemistry. Building relational inductive biases into deep learning architectures is crucial for creating systems that can learn, reason, and generalize from this kind of data. Recent years have seen a surge in research on graph representation learning, including techniques for deep graph embeddings, generalizations of convolutional neural networks to graph-structured data, and neural message-passing approaches inspired by belief propagation. These advances in graph representation learning have led to new state-of-the-art results in numerous domains, including chemical synthesis, 3D vision, recommender systems, question answering, and social network analysis. This book provides a synthesis and overview of graph representation learning. It begins with a discussion of the goals of graph representation learning as well as key methodological foundations in graph theory and network analysis. Following this, the book introduces and reviews methods for learning node embeddings, including random-walk-based methods and applications to knowledge graphs. It then provides a technical synthesis and introduction to the highly successful graph neural network (GNN) formalism, which has become a dominant and fast-growing paradigm for deep learning with graph data. The book concludes with a synthesis of recent advancements in deep generative models for graphs—a nascent but quickly growing subset of graph representation learning. |

| chemthink covalent bonding: Educational Interpreting Elizabeth A. Winston, 2004 This incisive book explores the current state of educational interpreting and how it is failing deaf students. The contributors, all renowned experts in their field, include former educational interpreters, teachers of deaf students, interpreter trainers, and deaf recipients of interpreted educations. Educational Interpreting presents the salient issues in three distinct sections. Part 1 focuses on deaf students--their perspectives on having interpreters in the classroom, the language myths that surround them, the accessibility of language to them, and their cognition. Part 2 raises questions about the support and training that interpreters receive from the school systems, the qualifications that many interpreters bring to an interpreted education, and the accessibility of everyday classrooms for deaf students placed in such environments. Part 3 presents a few of the possible suggestions for addressing the concerns of interpreted educations, and focuses primarily on the interpreter. The contributors discuss the need to (1) define the core knowledge and skills interpreters must have and (2) develop standards of practice and assessment. They also stress that interpreters cannot effect the necessary changes alone; unless and until administrators, parents, teachers, and students recognize the inherent issues of access to education through mediation, little will change for deaf students. |
| chemthink covalent bonding: An Introduction to Chemistry Mark Bishop, 2002 This book teaches chemistry at an appropriate level of rigor while removing the confusion and insecurity that impair student success.

| chemthink covalent bonding: Diane: A Signature Life Diane von Furstenberg, 2013-03-26 The frank and compelling story of an extraordinary woman and her adventures in fashion, business, and life. “Most fairy tales end with the girl marrying the prince. That's where mine began,” says Diane Von Furstenberg. Von Furstenberg lived the American Dream before she was thirty, building a multimillion-dollar fashion empire while raising two children and living life in the fast lane. Her wrap dress, a cultural phenomenon in the seventies, hangs in the Smithsonian Institution; her entry into the beauty business in 1979 was as serendipitous and as successful. Von Furstenberg learned her trade in the trenches, crisscrossing the country to make personal appearances at department stores, selling her dresses and cosmetics. That business had its ups and downs, as the fashionista entrepreneur’s unparalleled success became the source of its own undoing and she contended with bankruptcy, the loss of her business, and finally a complete self-reinvention that took her back to the top of the industry. This revealing and contemplative memoir works to make sense of the contradictions of the author’s life: glamour vs. hard work, European vs. American, daughter of a Holocaust survivor vs. wife of an Austro-Italian prince, mother vs. entrepreneur, lover vs. tycoon. She emerges wiser, stronger, and ever more determined never to sacrifice her passion for life. |

Fashion begets fashion, and life—from economics to politics, weather to warfare, practicality to the utterly impractical—is reflected in the styles of any given era, evolving into the threads you buy and wear today. With the candidness, intelligence, and charm that made him a household name on Project Runway, Tim Gunn reveals the fascinating story behind each article of clothing dating back to ancient times, in a book that reads like a walking tour from museum to closet with Tim at your side. From Cleopatra’s crown to Helen of Troy’s sandals, from Queen Victoria’s corset to Madonna’s cone bra, Dynasty’s power suits to Hillary Clinton’s pantsuits, Tim Gunn’s Fashion Bible takes you on a runway-ready journey through the highs and lows of fashion history. Drawing from his exhaustive knowledge and intensive research to offer cutting-edge insights into modern style, Tim explains how the 1960s ruined American underwear, how Beau Brummell created the look men have worn for more than a century, why cargo capri pants are a plague on our nation, and much more. He will make you see your wardrobe in a whole new way. Prepare to be inspired as you change your thinking about the past, present, and future of fashion! |
