Since platinum is metallically bonded and such elements are considered to have a formula unit of one atom, the answer is Avogadro's Number, 6.022 X 1023.
An atom of chlorine has 17 protons.
It depends on what atom it is, the number of protons in the nucleus of an atom or ion defines what type of atom it is.

When it has no charge there are 78.the number of electrons is always equal to the number of protons, both are the atomic number. the atomic number of platinum is 78, so 78 electrons and 78 protons too.
The atomic number of fluorine is 9. So there are 9 protons
Protons won't be found in an electron shell. They are concentrated in the nucleus.
The atomic number of platinum is 78. So there are 78 protons and 78 electrons.
