The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
Mg2+: [1s22s22p6]
Magnesium, ion (Mg2+)
Mg3P2
Mg2+
The reaction is:3 MgSO4 + 2 Na3PO4 = Mg3(PO4)2 + 3 Na2SO4
Mg3N2
The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
Mg2+: [1s22s22p6]
MgCl2 is formed. Mg2+ + 2Cl- ----> MgCl2
Magnesium, ion (Mg2+)
Mg2+
There are 10 electrons in an Mg2+ ion.
MgF2 Mg +F2 -> MgF2 MgF2 is ionic- it consists of Mg2+ and F- ions in a 1: 2 ratio.
The formula and charge for the carbonate ion is CO32- and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium carbonate, MgCO3.
Mg3P2
The formula and charge of the nitrate ion is NO3-, and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium nitrate, Mg(NO3)2.
