there are 12 protons in an atom of magnesium:-)
All magnesium atoms, regardless of the isotope, have 12 protons.
The periodic table states that the atomic number of magnesium is 12. A magnesium atom would thus have 12 protons in its nucleus; any atom that has 12 protons must be a magnesium atom. Atomic number = number of protons
This is about magnesium element. Mg atom contains 12 protons.
Magnesium has 12 protons. Bear in mind that ionization has no effect on the number of protons, so the "2 plus" is unnecessary. Magnesium always has 12 protons, that is the definition of magnesium.
