polarizability/polarizing power test 3

Postby Layla Manoochehri » Sat Dec 08, 2018 9:08 pm

"order these anions in order from least to most polarizable: At^-, Cl^-, O^2-, N^3-"

"order these cations in order from least to most polarizing power: Be^2+, Sr^2+, Rb^+, Na^2+"

I got these wrong on the test (question 6), can anyone tell me what the right order was for them? thanks!

O2- < N3- < Cl- < At-
Polarizability is a measure of how easily an atom's electron cloud can be distorted. Larger/less electronegative atoms will more polarizable.

Rb+ < Sr2+ < Na2+ < Be2+
Polarizing power is a measure of how easy it is to distort another atom's electron cloud. Smaller, more highly charged atoms will have a greater polarizing power.

polarizability increases down a group and decreases across a period, because more electronegative atoms are harder to remove an electron from

polarizing power decreases down a group and increases across a period, because smaller, more highly charged cations have greater power
