Answer 2

(a) A “good fit” is considered to be one where the cation can touch all of its nearest neighbor anions.

Explanation:

• A solid crystal is made up of cations and anions which come together to form a lattice.

• The cations being small in size are arranged in voids.

• These voids are formed when large anions come together to contribute to the formation of the lattice. For example, If 4 anions are forming a 2D lattice, then each anion is in contact with the rest 3 anions.

• When the cations settle in the voids such that they are in contact with anions from all sides they are considered to be a '"good fit" because it is touching all of its neighbor anions.
