Oxidation of Magnesium (Mg)

Today,from this post we will learn about the oxidation of magnesium (Mg).

Remember that the oxidation of magnesium (Mg) means the oxidation number of magnesium (mg) , the oxidation state of magnesium (Mg) or how many electrons magnesium (mg) usually loses.

To know the oxidation of magnesium (Mg),at first we have to find out the valence electrons in magnesium (Mg) from its electronic configuration.

Mg(12)=1s² 2s² 2p⁶ 3s²

=【Ne】3s²

Magnesium (Mg) is a metal.So it will lose electrons from its valence
Valence shell.Valence shell is the outer mostshell and valence electrons are the electrons of valence shell.

Mg(12)=1s² 2s² 2p⁶ 3s²

=【Ne】3s²

So,magnesium (mg) has 2 valence electrons.

During reactions (as we know that only valence electrons can take part) magnesium can lose maximum two electrons.

Usually, magnesium (mg) shows +1, and+2,oxidation number or oxidation states.

For showing +2 oxidation state,magnesium (mg) lose two electrons from 3s orbital.

For showing +1 oxidation state,magnesium (mg) lose one electrons from 3s orbital.

Now consider the following example:

◆MgCl₂

In this compound ,the oxidation of magnesium
is +2

◆MgCO₃

In this compound ,the oxidation of magnesium is +2.

●MgS

In this compound ,the oxidation of magnesium is +2.

◆In coordination compound,Mg has +1 oxidation number.
