Biology Water molecule

Oxygen has 6 outer shell electrons while Hydrogen has one each
Hydrogen bonds to oxygen sharing an electron each. Thus Oxygen has a complete outer shell... Why does water have two lone pairs? From where

can you see the "lone pairs" on the oxygen in the water molecule? they are the pairs of electrons in the outer shell which are not part of a bond.
the "bonding pairs" are the pairs of electrons involved in a bond, in this case in the covalent bond between oxygen and a hydrogen

the result of all this electron-sharing is that the oxygen has a complete outer shell (8 valence electrons) and each hydrogen has a complete outer shell (2 valence electrons).
