Electrons and Ions

The video explains that atoms are the fundamental units of nature, composed of protons, electrons, and neutrons. It discusses how atoms can become ions through the loss or gain of electrons, leading to the formation of ionic bonds. Examples such as sodium chloride and calcium chloride illustrate the occurrence of ionic bonds in nature. The video also covers the formation of ionic crystals and their properties.
