Polarizing power and polarizability

Postby melissa_dis4K » Wed Nov 28, 2018 10:35 pm

Can someone please explain polarizing power and polarizability in an easy way for me to understand? I don't understand the definition. Thank you

Polarizability is the how easily the electrons in an atom can be distorted (moved away from the nucleus) with higher polarizability being electrons more easily displaced from the nucleus.
Polarizing power is how good an atom is at polarizing another atom.

Polarizability is usually used to describe anions and polarizing power is usually used for cations.

Polarizing Power are when the cations pull electrons away from anions, and the smaller and more positive the cation the stronger their pull. Polarizability is how easily an electron cloud is distorted by an electronic field.

Polarizability is the measure of an atom's electron cloud's ability to become distorted by an anion. Polarizability follows the same trend as atomic radii on the periodic table.
