Nitrogen molecule is a nonpolar covalent molecule.(A) True(B) False

The statement "Nitrogen molecule is a nonpolar covalent molecule" is **true**.

Here's why:

1. **Molecular Structure**: A nitrogen molecule (\(\text{N}_2\)) consists of two nitrogen atoms. These two atoms are identical, so they have the same electronegativity.

2. **Bond Type**: The bond between the two nitrogen atoms is a covalent bond. Each nitrogen atom shares three pairs of electrons with the other nitrogen atom, forming a triple bond.

3. **Polarity**: Since both atoms in the nitrogen molecule have the same electronegativity, the electrons in the covalent bond are shared equally. There is no difference in charge distribution across the molecule, so there is no dipole moment.

4. **Molecular Polarity**: Because the molecule is symmetric (diatomic with identical atoms) and the electronegativity is the same, there are no regions of partial positive or negative charge. Thus, \(\text{N}_2\) is nonpolar.

In summary, the nitrogen molecule is nonpolar because the electrons are evenly shared between the two identical nitrogen atoms, resulting in no overall dipole moment.
