1. Atoms

3. Electrons

4. 3 pairs

5. Complete transfer of electrons

6. London dispersion forces

7. Energy

Explanation:

Atoms are the building block from which a compound is formed so we can say that composition of compounds depends on type of atoms. Electrons are shared unequally in a polar bond due to difference in electronegativity values of bonded atoms. There are 3 pairs of electrons are shared in nitrogen molecule. The transfer of electrons occurs from one atom to another in the formation of ionic bonds. London dispersion forces are the intermolecular forces that is responsible for the low melting and boiling points of a molecule or compound. Energy is needed to break the bonds that is present between the two bonded atoms.

the answer is definitely c.
