This seems rather a random question.
In what context is it being asked?

The proton number of an element defines what element it is: H has just 1 proton, He has 2, Li has 3, etc. etc.

Similarly The number of protons that H has is 1, He has is 2, etc. etc. So I see no difference.

BUT, if the two statements are related to two completely different things, I may have an answer. For example, if you are asked 'What is the number of protons on ethanol?', then what is being asked is not 'add up all the protons on all of the atoms' [which arguably could be the 'proton number' of ethanol], but instead, it means 'How many hydrogen atoms are attached to ethanol'

Chemists are sometimes lazy and call hydrogen a proton (because that's all it is), so the number of protons on a molecule means the number of hydrogens.

Does that help?

It's the same thing but the word order is different...

The words that make up the phrase is slightly different...

But it is certainly a random question..




Presumably it is a question that has been set in somebody's homework (or parts from different questions), so you shouldn't be so quick to dismiss!
