1. The Octet Rule and Lewis Structures of Atoms
The octet rule and the Lewis dot structure both provide valuable insight into the organization of an atom's valence electrons. Explore the intricacies of the octet rule and learn about the Lewis structures of atoms.
2. Valence Electrons and Energy Levels of Atoms of Elements
Valence electrons are the outer electrons in an atom that participate in chemical reactions and determine chemical changes to atoms and molecules. Learn about valence electrons, the significance of orbital location, and how to represent the number of valence electrons in a Lewis dot diagram.
3. Chemical Bonds II: Ionic
An ionic bond occurs when a single valence electron is given to an atom with only seven valence electrons to complete its outer electron shell. Discover key information about valence electrons, electronegativity, elements such as sodium and chlorine, and the process of creating ionic bonds.
4. Ions: Predicting Formation, Charge, and Formulas of Ions
The octet rule explains how ions are formed. Learn about this rule and use it to predict an ion's formation, charge, and formula, and also understand the role of cations and anions in this process.
5. Chemical Bonds I: Covalent
Learn how an atom shares electrons and form covalent bonds. Explore topics such as how valence electrons are formed, how molecules are made, how a covalent bond is made, the making of double and triple bonds, and the structure of a molecule.
6. Metallic Bonding: The Electron-Sea Model & Why Metals Are Good Electrical Conductors
Metallic bonding is known as the electron-sea model. Learn about metallic bonding with an explanation of the unique properties of metals, and understand why metals are good electrical conductors.
7. What is a Metallic Bond? - Definition, Properties & Examples
The metallic bond is a type of chemical bond that occurs between atoms of metallic elements. It gives metals their unique properties that we don't see in nonmetal substances, as you'll learn in this lesson.
