Every chlorine atom has 17 protons, 17 fundametal positively charged nuclear particles.

Explanation:

Elemental identity is defined by the number of protons, fundamental, massive, positively charged nuclear particles. The number of protons give #Z#, the atomic number, the which determines elemental identity: #1# for #H#; #2# for #He#;.......and #17# for #Cl#.

Do you have to remember these numbers? NO, because for every test in Chemistry and Physics you will ever sit, you should be supplied with a Periodic Table of Elements as a matter of course. You still have to be able to use the Table, so get on the case.
