Question

The explanation for the presence of three unpaired electrons in the nitrogen Atom can be given by?

Answer 1

The presence of three unpaired in Nitrogen can be explained by Hunds rule.

The atomic number of nitrogen is 7

So its electronic configuration will be - 1s2 2s2 2p3

Since the outer most shell is the p shell and P shell has 3 orbitals.

Each of these orbitals can accommodate 2 electrons. But these orbitals are filled according to the Hunds rule which states that pairing can only start after each orbital is singly filled.

Thus each of these 3 electrons occupies one orbital and remain unpaired.
