Question

The equation of a chemical reaction given below Mg+F2=MgF2 1. Which atom loses electrons in this reaction? 2. How many electrons are lost in this reaction?

Answer 1

Answer:

Explanation:

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.
