49. Identify the noble gas that has atoms in the ground state with the same electron configuration as the nitrogen in a molecule of isocyanic acid

Neon (Ne)

Explanation:

Nitrogen in it's neutral state has valency of 5 and it's electronic configuration is  given as;

1s2 2s2 2p3

However in isocyanic acid, it forms a covalent bond with hydrogen and carbon. Due to this bond, it is able to achieve stable octet configuration. The configuration is given as;

1s2 2s2 2p6

This is the same electronic configuration as Neon
