Answer:
C. Nitrogen
Explanation:
Nonpolar covalent bonds are a type of bond that occurs when two atoms share a pair of electrons with each other. An example of a nonpolar covalent bond is the bond between two hydrogen atoms because they equally share the electrons.
A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pair.
The element with the same electronegativity value aas Cl is the correct option.
This is Nitrogen.
