Magnesium has an atomic number of 12, which means its neutral atom has 12 electrons. hope it helps. svjetionici u hrvatskoj

"WebbFor the calcium two plus ion, so if you're thinking about forming an ion here, we're talking about the electron configurations for a neutral atom meaning equal numbers of protons and electrons. With the atomic number of 20, 20 protons and 20 electrons. If we lose two electrons, we have a net deposited two charge. We form the calcium to ion. " - Standard atomic notation for magnesium
