An atom consists of three subatomic particles.
In the middle of atom it consists of nucleus which have two subatomic particles. They are protons and neutrons.
And there is a subatomic particle that is found orbiting around the nucleus in an atom, name of that subatomic particle is electron.

Non polar covalent bond. The Cl's electronegativity is the same since it's the same atom. Therefore, they will be nonpolar
