Answer: The chemical formula for magnesium sulfite is [tex]MgSO_3[/tex]
Explanation:
The given compound is formed by the combination of magnesium and sulfite ions. This is an ionic compound.
Magnesium is the 12th element of periodic table having electronic configuration of [tex][Ne]3s^2[/tex].
To form [tex]Mg^{2+}[/tex] ion, this element will loose 2 electrons.
Sulfite ion is a polyatomic ion having chemical formula of [tex]SO_3^{2-}[/tex]
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the chemical formula for magnesium sulfite is [tex]MgSO_3[/tex]
