Polarity vs Polarizability

Postby Hannah Lee 2F » Sun Nov 03, 2019 8:00 pm

What is the relationship, if any, between polarity and polarizability? Can polarizability contribute to nonpolar covalent bonds?

Polarity is how charged an atom is. Polarizability is how likely it is to induce a dipole with another molecule. So the more polar a bond is, the more likely it is to polarize another molecule.

An atom that is highly polarizable if their electron cloud can readily undergo a large distortion while an atom that has high polarizing power can cause large distortions.

Polarizability is the ability of an atom to form temporary dipoles. In other words, it is the ability to be polarized by another. Polarizing power is the ability to polarize another.
Typically a bigger atomic radius means higher polarizability because a bigger electron cloud is more easily distorted. Polarizing power is the opposite in that a smaller atomic size has more polarizing power.
