Highly Polarized

What does highly polarized mean in terms of ionic bonds being more or less covalent?

Highly polarized means that a bond is getting closer to becoming ionic because it has a large difference in its atom charges, and one is pulling the electrons a lot more closer than the other.

Highly distorted electrons (from a large anion with weaker pull, for example) are described as being highly polarizable, which results in an ionic bond with more covalent character. Ions which cause large distortions have high polarizing power (cation).

Anions usually have strong pulls, while cations usually have weak pulls, because in an ionic bond the anion, which is very electronegative, takes the electron away from the cation to form a bond instead of sharing it like a covalent bond. If the anion becomes weaker, and the cation becomes stronger, then there is more of a "sharing" present between the cation and anion as opposed to the anion being much stronger and holding onto the electron(s) from the cation permanently.
