_ Mg +_ F2 → _ MgF2
Balance the following chemical equation

The metal loses electrons, and in forming  M g 2 +it loses 2 electrons and is oxidized:M g ( s ) → Mg 2 + + 2 e −( i )And on the other hand chlorine is reduced to chloride ion by accepting electrons:C l2 ( g ) + 2 e − → 2 C l −   ( i i )And  ( i ) +( i i ) =M g ( s )+ C l 2 ( g ) → M g C l 2 ( s )Both charge and mass are balanced, as required.
