Mg2+
Mg+2.
Mg+2.
A magnesium ion will be smaller because there will be a greater Zeff on the electrons in the magnesium ion due to a greater number of protons in the nucleus.
When an atom loses an electron, it becomes positive (Since you're taking away something that is negative). It would not become an ion, it would become a cation.
They form an Ionic compound.
+2 charge for magnesium ion
Mg2+
it is +2. the ion is represented as Mg2+.
Mg2+
MgO. Both the magnesium cation and the oxide anion are divalent, so that each ion neutralizes the charge of the other ion.
It would just be called an ion of magnesium. There is only one oxidation state for magnesium.
no, Cl is bigger
the symbol for the magnesium ion is Mg2+
Mg+2.
Magnesium once formed an ion the charge is 2+ .
Magnesium 2+
Magnesium forms a 2+ ion by giving away its two outermost electrons.
Cl-1.
