12
Magnesium's atomic number is 12. Thus, neutral magnesium would have 12 electrons. Mg2+ therefore has 2 less electrons, or 10.

It an atom has 12 electrons and is neutral, then it must be Mg (magnesium), and magnesium has 2 valence electrons which would be used in bonding.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
A neutral magnesium atom has 12 protons ans 12 electrons.
No, the element with an atomic number of 12 is magnesium (Mg), which contains 12 protons and 12 electrons in a neutral atom. If Mg 2 refers to a magnesium ion with a 2+ charge, it would have lost two electrons, resulting in 10 electrons.
Magnesium, Mg, atom number 12, 12 protons and 12 electrons.
Magnesium and the rest of the alkaline earth metals have two valence electrons.
This element is magnesium (Mg); the atom in the neutral state.
The Magnesium atom will lose 2 of its electrons to become a Magnesium ion with 10 electrons. (Mg2+) How many electrons does a magnesium ion have? How many electrons does a fluoride ion have? How many electrons does a fluoride ion have?
A Mg2+ ion has lost two electrons compared to the neutral magnesium atom. As a result, it has 10 electrons.
