Non-bonded Electrons in NO2− | JEE Main PYQ | Chemical Bonding
Total number of non-bonded electrons present in NO2− ion based on Lewis theory is ______.

Correct Answer: 12

Explanation

Total valence electrons in NO2− :

N = 5, O = 6 × 2 = 12, extra electron = 1

Total = 18 electrons

Number of bonding electrons = 6

Non-bonded electrons = 18 − 6 = 12
