It varies. Every different element (ie every different substance) has a different number of protons in its atoms. eg Hydrogen atoms have one proton, Helium atoms have two protons, Lithium has three and so on up to 92 in nature.
There are 14 protons in one atom of Silicon
One atom of potassium contains 19 protons.
There will be 9 protons in a fluorine atom, but actually, there exists only fluorine-19.
A sodium atom has 11 protons.
There are 9 protons in the element fluorine.
There are 14 protons in one atom of Silicon
One atom of potassium contains 19 protons.
5 protons in one atom of boron. look at the periodic table.
There are 37 protons in one atom of rubidium-85.

There are many sources one can search for how many protons are in an atom. The easiest source one can search is the very famous periodic table of elements.
Every element has a different number of protons.
Lawrencium has 103 protons.
The atomic number of an element gives its number of protons per atom. Sodium's atomic number is 11. Thus, sodium has 11 protons per atom.
