Polarizing Power

Postby AlyssaBei_1F » Mon Nov 12, 2018 1:57 pm

Can someone explain to me how we determine polarizing power?

High polarizing power means it's smaller, has a higher effective nuclear charge, and higher electronegativity.

Polarizing power is used to describe cations, which pull electrons away from the anions. Smaller, more positive cations would pull electrons more strongly, so they have more polarizing power (ex. Mg 2+ is small and positive so it has more polarizing power).

Polarizability is the term we use to refer to a low electron affinity/electronegativity element's ability to have its electrons pulled away from it. The higher the polarizability, the more likely it is to form a bond with covalent character.

Polarizing power refers to the power of an atom to induce a dipole in another atom. It is the opposite of polarizability, which is how easy it is for an atom to turn into a dipole.Atoms with high polarizing power are light cations.

Polarizing power is the ability of a cation to distort an anion. Small cations have the greatest polarizing power because there is a greater concentration of positive charge in a smaller area, attracting the electrons from the anion.
