12 protons means your element is atomic number 12 = Mg
12 positive protons added to 10 negative electrons leaves a charge of +2.
So the ion is Mg+2

Rb is an alkali metallic so it shows in actual fact +a million even even though it quite is totally electropositive Br shows -a million P may even loos it quite is elec.To show +3,+4,+5 and can take elec. To finally end up P-3 In is a A III factor it would loose elec.a million,2or3 Ra we dont communicate of ox. Or relief of Ra as that's nuclear lively element those forms of numbers in basic terms count upon what reaction are they are going by making use of potential of
