How many nonbonding electron pairs are there in the lewis structure of the peroxide ion

DENIUS [597]

Answer:

There are 6 non bonding pair of electrons present in Lewis structure of peroxide ion.

Explanation:

Ionic formula of peroxide ion is $O_{2}^{2-}$

Total number of valence electron present in peroxide ion is 14 (12 electrons come from two oxygen atoms and another 2 electrons come from negative charges).

After fulfilling octet rule, Lewis structure of peroxide shows that each oxygen atom contains three non bonding electron pairs and a covalent bond.

Hence there are 6 non bonding pair of electrons present in Lewis structure of peroxide ion.

Lewis structure has been given below.
