Ionic Bonding and Naming Compounds Essentials

This video tutorial covers the basics of ionic compounds, including their formation, properties, and naming conventions. It explains chemical bonds, the octet rule, and the formation of cations and anions. The video provides examples of calcium and oxygen ions and discusses the properties of ionic compounds, such as their crystal lattice structure. Finally, it outlines the rules for naming ionic compounds, with examples.

What is the octet rule?

• Atoms gain, lose, or share electrons to have ten electrons in their outermost energy level.

• Atoms gain, lose, or share electrons to have four electrons in their outermost energy level.

• Atoms gain, lose, or share electrons to have six electrons in their outermost energy level.

• Atoms gain, lose, or share electrons to have eight electrons in their outermost energy level.
