General Chemistry: Polarity of Molecules

Equal or unequal sharing of electrons among atoms of molecules.

Atoms tend to gain, share, or transfer electrons in order to attain a stable 8 valence electrons.

The relative ability of an atom to draw electrons in a bond toward itself. The greater the electronegativity difference, the greater the polarity of the molecule.
