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.
"As many as it has electrons" (if there are a different number of protons to electrons then it has a net charge and it is an ion, not an atom)
All atoms have at least one proton.
The number of protons defines which atom it is, hydrogen atoms have 1 proton, helium atoms have 2, lithium 3 and so on...
And it depends what the atomic number is.
1,1,1
There are 14 protons in one atom of Silicon
19
That would depend on how many protons exist in the nucleus of the atom. An atom with 6 protons is a carbon atom; 7 protons is nitrogen, and 8 = oxygen.
17 protons and 17 electrons if it is a neutral atom 17 protons and 18 electrons in a -1 Cl 17 protons and 16 electrons in a +1 Cl
Oxygen has 8 protons in the atom.
There are 14 protons in one atom of Silicon
5 protons in one atom of boron. look at the periodic table.
9
Every element has a different number of protons.
Lawrencium has 103 protons.
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.
One
32
11
There are 18 protons in an Aragon atom.
An atom of copper has 29 protons.
