Exploring Ionic Chemical Bonding

The video tutorial explains the formation of ionic bonds, focusing on how atoms achieve stability by transferring electrons. It covers the creation of ions, specifically cations and anions, using examples like sodium and chlorine. The tutorial also discusses the interaction between these ions, such as in sodium chloride, and the formation of compounds like calcium chloride. Finally, it provides rules for determining when ionic or covalent bonds will form based on the elements involved.

What is the main goal for atoms in terms of their energy levels?

• To lose all electrons

• To fill their outermost energy level

• To gain protons

• To become unstable
