5.1: BONDING 
Atoms are rarely found in their elemental form but are usually found bonded to other 
atoms as part of compounds. A bond is composed of a group of negatively charged 
valence electrons between the atoms that simultaneously attract the positively charged 
nuclei of both atoms. Since the two atom nuclei are attracted to the same group of 
electrons, they remain together. Atoms bond because are more stable together. They are 
more stable together because energy is released in the bond...
