Covalent bonding occurs when atoms share electrons to achieve a stable electron configuration, typically a full outer shell. Diagram 1: Hydrogen (H₂) Each hydrogen atom has 1 electron. They share their electrons so each atom effectively has 2 electrons (like Helium). H • + • H → H : H (or H-H) Diagram 2: Water (H₂O) Oxygen needs 2 more electrons to complete its outer shell (it has 6). Each hydrogen needs 1 more electron (they have 1). Oxygen shares one electron with each hydrogen, and each hydrogen shares its electron with oxygen. • • :O: • • / \ H• •H becomes • • :O: • • / \ H: :H (The dots represent valence electrons. The 'H: :H' part shows the shared pairs forming covalent bonds.)
