The valence electrons are given up by H and gained by Br. This results in 2 ions that are oppositely charged and they are attracted to each other by the charges.

If the valence electrons are shared in a bond (equally or unequally), this is a covalent bond. Equally shared is a nonpolar covalent and unequally shared is a polar covalent bond.
