Step 1: Consider the electronic configuration of a nitrogen atom.
Nitrogen (N) has an atomic number of 7.
Its electronic configuration is .
It has 5 valence electrons (2 in 2s and 3 in 2p).
Step 2: Determine how nitrogen atoms bond to form a nitrogen molecule (N ).
To achieve a stable octet (like neon), each nitrogen atom needs to gain 3 more electrons.
In the N molecule, the two nitrogen atoms share three pairs of electrons, forming a triple covalent bond.
N N
Each nitrogen atom contributes 3 electrons to the bond, and each also has one lone pair of electrons ( ).
Step 3: Identify the type of bond.
The bond between the two nitrogen atoms in an N molecule is a triple bond.
Option (4) "Multiple bond" is a general term that includes double and triple bonds, but "Triple bond" is more specific and accurate.
This matches option (3).
