Nitrous ___ (laughing gas) (5)

Ross

I believe the answer is:

oxide

(Other definitions for oxide that I've seen before include "Compound of oxygen and one other element" , "Rust is iron -" , "Compound such as rust" , "Oxygenous compound" , "Compound of two elements, one with atomic number 8" .)

I've seen this clue in The Washington Post.
