A polar covalent bond is created when one atom in a bond is more electronegative than the other. What this means is that the electrons from that bond have a greater draw to the more electronegative atom than the other. Since electrons tend to move around quite a bit within the molecular orbitals that are formed between two atoms, what is happening to the electrons is that over time they are spending more time on the electronegative atom than on the less electronegative atom.

The atoms join together, and the electrons are shared between atoms so at each atom has a turn at having a full outer shell.
