Mg2+ .................................

Answer: The magnesium ion formed is [tex]Mg^{2+}[/tex]

Explanation:

Magnesium is the 12th element of the periodic table having electronic configuration: [tex]1s^22s^22p^63s^2[/tex]. This element will easily loose 2 electrons and form [tex]Mg^{2+}[/tex] ion.

Sulfur is the 16th element of the periodic table having electronic configuration: [tex]1s^22s^22p^63s^23p^4[/tex]. This element will easily gain 2 electrons and form [tex]S^{2-}[/tex] ion.

Sulfur and magnesium will form ionic compound, which means that a complete transfer of electrons takes place from one element to another.The compound formed will be MgS (Magnesium sulfide).

Hence, the magnesium ion formed is [tex]Mg^{2+}[/tex]
