What are the number of protons in an every isotope?

There is no set number of protons in an isotope. The definition of an isotope is an atom that has the same number of protons but a different number of neutrons. Therefore, the answer to the question is; the number of protons in an isotope remain the same. To know the number of protons, look at the Periodic Table. The Atomic Number is the number of protons. Don't confuse that with Atomic Mass - To confirm, the Atomic Numbers for Hydrogen and Helium are 1 and 2.
