<u>Answer:</u> The oxidation number of magnesium in magnesium chloride is +2.

<u>Explanation:</u>

Oxidation number is defined as the number that is assigned to an element when it gains or looses electrons. If an element gains electron, it will attain a negative oxidation number and if an element looses electron, it will attain a positive oxidation number.

The chemical formula for magnesium chloride is MgCl_2

We take the oxidation state of magnesium atom be 'x'.

Oxidation state of chlorine atom = -1

Evaluating the oxidation number of magnesium atom:

x+2(-1)=0\\\\x=+2

Hence, the oxidation number of magnesium in the given compound is +2.
