That depends on the type of atom. there are several different elements, (see a Periodic Table) and it increases from left to right. Hydrogen has one proton , helium has two protons and lithium (below hydrogen) has three. The number above the element name is the number of protons it has.
There are 18 protons in an Aragon atom.
An atom of copper has 29 protons.
An atom of carbon has 6 protons.
An atom of chlorine has 17 protons.
there are 12 protons in an atom of magnesium:-)
There are 26 protons in the atom of iron.
A technetium atom has 43 protons.
A sodium atom has 11 protons.
There are 9 protons in the element fluorine.
there are 7 protons in each nitrogen atom.
An atom of chlorine has 17 protons, while an atom of sodium has 11 protons. Therefore, an atom of chlorine has 6 more protons than an atom of sodium.
There are 17 protons in the nucleus of an atom of chlorine.
