why do elements form chemical bonds
Why do most atoms form chemical bonds. An attraction between atoms and/or molecules will lead to chemical bonding. An atom is always looking for the most stable configuration for its electrons. Bonding allows many atoms to form stable compounds.
Most atoms need 8 electrons to complete their outer shell. So, an atom that has 2 outer electrons will often form a chemical bond with an atom that lacks two electrons to be complete. For example, a sodium atom has one lone electron in its outer shell.
