Explanation:

In water (\(H_2O\)), hydrogen has 1 valence electron and oxygen has 6 valence electrons. Covalent bonding occurs when atoms share electrons. Hydrogen needs 1 more electron to complete its outer shell (duet rule, as it has only the first energy level which can hold 2 electrons), and oxygen needs 2 more electrons to complete its outer shell (octet rule, as it has the second energy level which can hold 8 electrons). So, two hydrogen atoms each share 1 electron with the oxygen atom.

Answer:

share
