After an atom has lost an electron, it can be BEST described as an ion with

A. a positive charge and a smaller radius.
B. a negative charge and a smaller radius.
C. a positive charge and a larger radius.
D. a negative charge and a larger radius.

a) a positive charge and a smaller radius

as the atom loses this negatively charged particle, it will become more positive/less negative. since the positive charge of the nucleus of the atom will not change, the nucleus will still have the same "pull" inward on the outer electrons but with one less electron "pulling" back, thus pulling the remaining orbiting electrons closer in lessening the size of the overall atom.

A. It will have a positive charge because electrons are negative and one electron has been lost.
