Final answer:

The Ca²+ ion is smaller than the Ca atom due to electron loss, resulting in a smaller size.

Explanation:

The Ca²+ ion is smaller than the Ca atom. This is because when an atom loses electrons to form a cation, the remaining electrons are pulled closer to the nucleus, resulting in a smaller size. In this case, the Ca²+ ion has a radius of 99 pm compared to the Ca atom's radius of 197 pm.
