Practical tome is re-issued with fundamental things (6,9)

I believe the answer is:

atomic particles

I'm a little stuck... Click here to teach me more about this clue!

'fundamental things' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'practical tome is re-issued' is the wordplay.
'practical tome is' anagrams to 'ATOMIC PARTICLES'.
However, I'm not clear how this is indicated.

'with' acts as a link.

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
