does polarizability and polarizing power relate to electronegativity and electron affinity? like do ions with high polarizability have a higher electron affinity and atomic radius? and do ions with a strong polarizing power have a low electron affinity, electronegativity, and small atomic radius?
I believe all these concepts are related. An anion will be more polarizable if it has a larger ionic radius and thus has a lower ionization energy/lower electron affinity. The effective nuclear charge is lower so the electrons are held less tightly and the electron cloud is more easily distorted to the cation. Conversely, a highly polarizing cation will have a smaller ionic radius and thus a higher electronegativity and electron affinity. It will want to draw the electrons from the anion in more, thus the high polarizing power.
What is the difference between polarizability and polarizing power?
