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...
