Elementary variation (7)

Ross

I believe the answer is:

isotope

(Other definitions for isotope that I've seen before include "Form of atomic nucleus" , "Oops, tie up the atom" , "Oo, spite! (anag.)" , "One of various forms of an elemental atom" , "One form of element, differing in its neutrons from another" .)

I've seen this clue in the Newsday.
