How does size affect polarizing power/ polarizability

[kellyz_1C]

I'm still a bit confused on how size affects these traits. Does it have something to do with electron shielding?

[Betty Wolkeba section 1L]

The larger the size, the more polarizability it has because larger atoms are usually easier to remove electrons from. However, the larger the size, the less polarizing power it has I believe.

[Isabelle De Rego 1A]

You can think of it like how much the atom wants to hold onto its electrons. A small atom is much more likely to hold onto its electrons than a large one because it has way less electrons to begin with. Therefore a large atom is more polarizable, or it is easier to take electrons from it. A small atom has more polarizing power because it can get closer to the anion and exert more force on its electrons. Also, a smaller atom, or highly charged atom wants the electrons more than a big atom, so it has more "power" to take them away.

Polarizability is directly related to size, while polarizing power is inversely related to size.
