For N1 the lone pair is in an sp 2 hybrid orbital and is not part of the aromatic system. Hence the protonated form is still aromatic. For N2, the lone pair is in a p orbital and most importantly is involved in the aromatic sextet. Lone pairs (shown as pairs of dots) in the Lewis structure of hydroxide 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.
