I believe the answer is:

ion

(Other definitions for ion that I've seen before include "Electrically-charged particle" , "Electrically charged particle" , "Electrically charged atom or group of atoms" , "Charged atom/molecule" , "Subatomic particle" .)

I've seen this clue in the Newsday, the USA Today, The New York Times and the LA Times.
