What is the bond character for Cl2?

The Cl₂ bond will be a nonpolar covalent bond.

Explanation:

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl. The shared electron pair is common to the two atoms and holds them together.

Electonegativity is defined as the ability of an element to attract electrons that link it to another element. This makes it possible to determine whether the covalent bond between two atoms is polar or nonpolar. If the atoms that form the bond are the same, the bond will be nonpolar (because the electronegativity is the same and no atom attracts electrons more strongly than shared electrons). But, if the atoms are different, the bond will be polarized towards the most electronegative atom, because it will be the atom that attracts the pair of electrons with more force. Then it will be polar.

The Cl₂ bond will be a nonpolar covalent bond.

The Cl atoms in a Cl2 molecule each attain an octet by sharing their unpaired electrons. There is one bonding pair in Cl2, which lies in the region of overlap of the two octet circles. pairs are called lone pairs. The two atoms have identical electronegativities, so the Cl-Cl bond is a nonpolar covalent bond.
