Question

What type of bond would be formed between nitrogen (N) and nitrogen (N)? Why?

Answer 1

Answer: The compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.

Explanation:

If electronegativity difference between two atoms is less than 0.4 then bond formed is a pure covalent bond.

If electronegativity difference between two atoms is between 0.4 to 1.8 then bond formed is a polar covalent bond.

If electronegativity difference between two atoms is greater than 1.8 then bond formed is an ionic bond.

The electronegativity value of a nitrogen atom is 3.04. Hence, the electronegativity difference of $N_{2}$ molecule is as follows.

$Electronegativity difference = electronegativity value of N - electronegativity value of N\\= 3.04 - 3.04\\= 0$As the electronegativity difference is 0 which is less than 0.4.

Hence, we can conclude that the compound formed between nitrogen (N) and nitrogen (N) a polar covalent bond because there is less than a 0.4 difference in electronegativity between the atoms.
