Why is a cation smaller than its parent atom?
It has fewer electrons than the parent atom.
Which ion has a larger ionic radius compared to its parent atom?
F- (Fluoride ion)
What leads to the increase in the size of an anion compared to its parent atom?
Addition of electrons leading to increased repulsion
