WHY LITHIUM BIGGER THAN FLUORINE?

Asked by  | 21st Feb, 2012, 09:53: AM

Expert Answer:

Lithium has a lower nuclear charge and is actually larger than fluorine. Its valence electron is not tightly held. Fluorine's high nuclear charge coupled with its small size make it hold onto bonding electrons more tightly than any other element.
