PPT-Polar Covalent

B onds Polar bond A type of covalent bond between two atoms in which electrons are shared unequally resulting in a bond in which one atom has a slightly negative charge and the other a slightly positive charge. Why do atoms bond?. Atoms gain stability when they share electrons and form covalent bonds.. Lower energy states make an atom more stable.. Gaining or losing electrons makes atoms more stable by forming ions with noble-gas electron configurations.. VSEPR Theory, Polarity, and using . Electronegativity. Covalent . Bonds.
