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)...

Oxidation of Nickel (Ni) Today,from this post we will learn about the oxidation of nickel. Remember that the oxidation of nickel means the oxidation number of nickel , the oxidation state of nickel or how many electrons nickel usually loses. To know the oxidation of nickel,at first we have to find out the valence electrons in nickel from its electronic configuration. Ni(28)=1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁸ =1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁸ 4s² =【Ar】3d⁸ 4s² Nickel is a transitional metal.So,we have to consider d orbital as part of its valence shell.Valence shell is the outer mostshell and valence electrons are the electrons of valence shell. Ni(28)=【Ar】3d⁸ 4s² So,nickel has 10 valence electrons.But this does means that nickel will use all the valence electrons during reactions as we know that only valence electrons take part during a reaction. Usually, nickel shows 0,+1,+2,+3 and +4 oxidation number or oxidation states. For showing +2 oxidation state,nickel lose two electrons...
