Covalent Bonds

Covalent bonding is a type of chemical bonding that occurs when electron pairs are shared between atoms.

-Substances with covalent bonds:

    Are usually not conductive.

    Are usually powdery or granular

    Usually have low melting points

    Are sometimes soluble in water

-In a nonpolar - covalent bond, electrons are shared equally between the atoms, so there is a balanced distribution of electrical charge.

-In a polar - covalent bond, the bonded atoms have an unequal attraction for the shared electrons.
