FREE Expert Solution

We’re being asked to identify the bonding pairs and lone pairs in water (H2O). We must first draw a Lewis structure for H2O

Determine the total number of valence electrons present in the molecule:


            Group            Valence Electrons

H        1A                   2 × 1 e = 2 e

O        6A                   1 × 6 e = 6 e

                        Total:  8 valence e
