Smallest particle of an element (4)

Ross

I believe the answer is:

atom

This clue is a double definition.

'smallest particle' is the first definition.
(I've seen this before)

'an element' is the second definition.
(thesaurus)

'of' acts as a link.

(Other definitions for atom that I've seen before include "Smallest particle in an element able to take part in a chemical reaction" , "It was once thought to be smallest particle of matter" , "Very small object or amount" , "Part of molecule" , "Basic unit of a chemical element" .)

I've seen this clue in The Times, The Guardian and The Telegraph.
