Polarizability vs. Polarizing Power

Postby somyapanchal1D » Fri Jul 12, 2019 7:34 pm

In discussion section we talked about two different periodic trends polarizability and polarizing power. What exactly are the differences between the two trends?

Polarizability -
- Generally for anions, are electrons that are further away from the nucleus
- more energy shells = more polarizability
Polarizing power- Generally for cations, are less electrons closer to the nucleus
- less electron shells = more polarizing power

Also, higher polarizable atoms are typically atoms with electrons that are far away from the nucleus, (many shells), and because the electrons are further away, the electron cloud is large and highly polarizable as denoted by the textbook. Also, cations are generally not highly polarizable because they typically have electrons closer to the nucleus, making them less prone to distortion. In terms of polarizing power, this is almost the converse: the atoms that cause the distortion and they are typically cations.

Super helpful, thanks!!
