Covalent Bonding and Electron Sharing

This video tutorial explains how to draw covalent bonds for various molecules, including hydrogen, hydrogen chloride, chlorine, methane, ammonia, water, oxygen, and nitrogen. It covers the concept of electron sharing between non-metals, the significance of the periodic table in determining outer shell electrons, and the formation of single, double, and triple bonds.

What is the primary characteristic of covalent bonding?
