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
Every atom, ion, and isotope of the same element will always have the same number of protons (12 in this case). An atom of magnesium without one or more protons or with more protons is no longer magnesium.
The magnesium cation has 12 protons. Magnesium typically has 12 protons in its nucleus, which gives it a positive charge when it loses electrons to become a cation.
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.
i don't know go back to school:) it's a cation!
The Cu+ cation is formed when a copper atom loses one electron. Therefore, it has one more proton than electrons. So, the Cu+ cation has 29 protons and 28 electrons.
Magnesium forms a divalent cation, Mg2+.
Magnesium typically forms a divalent cation with a charge of +2, meaning it loses two electrons to achieve a full outer shell.
magnesium has 12 protons
there are 12 protons in an atom of magnesium:-)
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.
All magnesium atoms, regardless of the isotope, have 12 protons.
This is about magnesium element. Mg atom contains 12 protons.

Magnesium sulfate is a salt; Mg2+ is the cation and (SO4)2- is the anion.
Magnesium always has 12 protons (both in neutral form and in ion form).
The Cu+ cation is formed when a copper atom loses one electron. Therefore, it has one more proton than electrons. So, the Cu+ cation has 29 protons and 28 electrons.
Each atom of the element magnesium contains exactly 12 protons.
