The atomic number of Mg (and not written as mg) is 12. So there are 12 protons and 12 electrons
Note:
Mg is the symbol for the element magnesium
mg generally stands for milli grams

That 2+ means that two electrons have been donated to another atom and a positive charge of 2+ is on the cation, so magnesium usually has 12 electrons and it's ion now has 10 electrons.

∙ 12y agoMg2, also known as magnesium 2, has approximately 10 electrons because its atomic number is 12. You'd subtract 2 from the atomic number and that results in your electron count.

∙ 13y agoMagnesium is a monoatomic molecule...
it exists as Mg.
Mg has a 12 electrons.

∙ 13y agoMg has 12 electrons but mg plus 2 has donated two electrons to another electro-negative element say B and has become Mg+2
so Mg has 10 electrons
Wiki User
∙ 13y agoMg2+ has 10 electrons (K,L,M = 2,8,0)
Mg2+ ions have an electron configuration of Neon: 1S2, 2S2 2P6, 3S0

How many electrons are in the valence shell for Mg?
Mg or Magnesium has 2 electrons in its Valence shell. If you have the right Periodic Table it should have numbers 1A, 2A,... 3B, ect listed above each column. These numbers represent the number of Electrons in the valence shell of all the elements in that Column.
How many electron proton and neutron does a mg2 plus ion have?
Mg has 12 protons, 12 electrons and 12 neutrons.Mg^2+ ion has 12 protons, 10 electrons and 12 neutrons. The number of protons and neutrons remains the same, but since the ion now has a 2+ charge, it has lost 2 electrons.
