Polar Molecule

A polar molecule is a molecule that has a slight positive charge on one end and a slight negative charge on the other end due to an imbalance in the way electrons are shared.^[1] The water molecule is an example of a polar molecule;^[2] the oxygen atom is more electronegative than the hydrogen atoms, so it pulls the electrons closer to it which gives it a slight negative charge. The hydrogen atoms, then, gain a slight positive charge.
