Polar Power

Postby Samantha Chang 2K » Tue Nov 27, 2018 11:28 pm

Can someone elaborate what polar power is? And why a high charge and a low volume affect it?

Polarizing power is basically an atom's ability to distort or effect an electron cloud around another atom. Ions have the highest polarizing power because they contain strong charges that have a high potential to distort other atoms. A smaller atomic radius means and a higher ion charge are usually characteristics of an atom with high polarizing power.

To be more specific, cations (positively charged ions) have high polarizing power. Anions would not have high polarizing power because they would not pull electron clouds as they are negatively charged. You typically refer to cations in terms of the polarizing power and anions in terms of their polarizability.

Polar Power Compared to Atomic Radius

Postby charlotte_jacobs_4I » Wed Nov 28, 2018 4:00 pm

Is the polar power only determined by the atomic radius? For this would it be the smaller the radius the larger the polar power?

The atomic radii helps you understand why the polarizing power increases or decreases since the size of the radius correlates with how much power the nucleus has on the valence electrons.
