Each atom has a different ability to draw

electrons to itself when it shares electrons (that drawing ability is

called Electronegativity).

A polar covalent means that an atom is electronegative, and the electrons are shared, but not equally.

So, if a bond between two atoms share electrons equally, then it is nonpolar and not electronegative.

If a bond between two atoms aren't shared equally, then it is polar and electronegative. Ex.) A polar molecule is water.
