Question

What is the number of pairs of electrons that are shared between the nitrogen atoms in a molecule of N2?

Answer 1

The answer is (3) 3. The sharing of electrons is important to help elements get 8 electrons in the outer shell to be stable. To achieve this aim, the nitrogen needs to share three pairs of electrons.

Answer 2

The number of pairs of electrons that are shared between nitrogen atoms in a molecule of ${{\text{N}}_{\text{2}}}$ is $\boxed{\left( 3 \right){\text{ 3}}}$.

Further explanation:

Covalent Bond

It is a type of chemical bond where electrons are mutually shared between the bonded atoms. This bond is also known as a molecular bond. The compounds formed as a result of this bonding are covalent compounds.

Octet Rule

It is a thumb rule that describes the tendency of elements to bond with other elements in order to acquire eight valence electrons. As a result, elements tend to achieve stable noble gas configuration.

The atomic number of nitrogen is 7 and it has an electronic configuration of $1{s^2}2{s^2}2{p^3}$. Nitrogen has five valence electrons in it and is three electrons short of the stable noble gas configuration of neon. So it can share three electrons with another nitrogen atom to complete its octet. As a result, three covalent bonds are formed between two nitrogen atoms. In other words, nitrogen atoms have a triple bond between them in   molecule (For structure, refer to the attached image).
