Polarizing

Postby Diana Sandoval 1K » Thu Dec 06, 2018 4:34 pm

How do we determine which atom is the most polarizable and also their polarizing power?

The more negative the charge of an anion (the greater the number of electrons compared to the number of protons) and bigger its ionic radius, the more polarizable it is. For example P3- is more polarizable than Cl-.

The more positive the charge of a cation (the greater the number of protons compared to the number of electrons) and the smaller its ionic radius, the greater its polarizing power. For instance, Ba2+ has greater polarizing power than Cs+.
