Size of a Cation Size of a Cation Why is the cation smaller than its parent atom (neutral)?

Size of a Cation Size of a Cation A cation is smaller than its parent atom. Why? Because metals will lose an energy level in the process of becoming a cation.

Size of an Anion Size of an Anion Why is an anion larger than its parent atom?

Size of an Anion Size of an Anion A anion is larger than its parent isotope. Why? Repulsion force increases as more electrons are added to the outer most energy level. Swells the energy level.
