Answer: The chemical formula for the compound formed will be [tex]BaS[/tex]
Explanation:
Barium is the 56th element of the periodic table having electronic configuration of [tex][Xe]6s^2[/tex]
This element looses 2 electrons and thus shows an oxidation state of +2 units.
Sulfur is the 16th element of the periodic table having electronic configuration of [tex][Ne]3s^23p^4[/tex]
This element requires 2 electrons and thus shows an oxidation state of -2 units.
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.
Thus, the chemical formula for the compound formed will be [tex]BaS[/tex]
