One mole of platinum contains Avogadro's number (6.022 x 10^23) of atoms. Since each platinum atom has 78 protons, one mole of platinum contains 78 times Avogadro's number, which equals 4.686 x 10^25 protons.
An atom of chlorine has 17 protons.
A technetium atom has 43 protons.
There are 88 protons in a radium atom.
78 protons, 78 electrons and 119 neutrons
Atomic number of it is 16. It has 16 protons in a atom.

There are 78 protons and 78 electrons present in a platinum atom. There are also at least 114 neutrons in the five stable isotopes. 192 Pt = 114 194 Pt = 116 195 Pt = 117 196 Pt = 118 198 Pt = 120

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
One mole of platinum contains Avogadro's number (6.022 x 10^23) of atoms. Since each platinum atom has 78 protons, one mole of platinum contains 78 times Avogadro's number, which equals 4.686 x 10^25 protons.
