Ionic Vs. Covalent

Why do atoms create chemical bonds when they come into contact with each other?

• Because atoms like high levels of energy.
• Because elements are afraid to be alone.
• Because atoms are much more stable with 8 valence electrons. (octet rule)
• Because atoms are much more stable with 8 valence electrons. (valence rule)
