Why size of action is always smaller than that of its neutral atom

1.	Why size of action is always smaller than that of its neutral atom
Answer» Because :-1. They have less electrons than parent atom since nuclear charge remains the same. So they are tightly held by the nucleus due to which the atomic size decreases.2. Also , as electron decreases the shielding effect ( electron - electron repulsion) decreases , due to this also cation is always smaller than its parent atom.
