Detailed explanation-1: -In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond and is sometimes called an unshared pair or non-bonding pair. Lone pairs are found in the outermost electron shell of atoms. They can be identified by using a Lewis structure.
Detailed explanation-2: -[If the answer is 2 and 4, represent as 24] SOLUTION In NOz ion, the number of bond pair and lone pair of electrons on nitrogen atom are 4 and 0 respectively. Hence, the answer is 40.
Detailed explanation-3: -The nitrogen atoms are bonded with triple bonds. So, each of them have a lone pair of electron. Hence, total number of lone pair is 2.
Detailed explanation-4: -NH3 molecule has one lone pair of electrons on the central atom i.e. Nitrogen.
