Why does chemistry happen?! Element Stability and the Octet Rule!

The video explains why ions form and elements bond, focusing on the concept of stability. Elements aim for a full outer shell of valence electrons, often following the octet rule, except for hydrogen and helium. Stability is achieved through ionic or covalent bonding. Examples include sodium losing an electron to form Na+ and chlorine gaining an electron to form Cl-. Helium, a noble gas, is stable with two electrons in its outer shell.

Describe the difference between ionic and covalent bonds as mentioned in the text.
