Rust compound (5)

Ross

I believe the answer is:

oxide

(Other definitions for oxide that I've seen before include "Rust, for instance" , "Compound of two elements, one with atomic number 8" , "Chemical compound" , "Compound of oxygen and one other element" , "Compound of oxygen with another element" .)

I've seen this clue in the King Feature Syndicate.
