Renegade entity won a number of uranium protons (6-3)

'a number of uranium protons' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'renegade entity won' is the wordplay.
I cannot really see how this works, but
an anagram of 'entity' is 'inetyt' which is located in the answer.
an anagram of 'won' is 'nwo' which is present in the left over letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
