Proton carriers (5)

Ross

I believe the answer is:

atoms

'proton carriers' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for atoms that I've seen before include "Little things" , "Minute particles" , "small fragments" , "Dots" , "Jots" .)

I've seen this clue in the L.A. Times Daily and the LA Times.
