Explain the reaction of chlorine with magnesium

Explanation

To explain the reaction of chlorine with magnesium, we can break it down into a series of steps:

### Step 1: Identify the Reactants
The reactants in this reaction are magnesium (Mg) and chlorine (Cl2). Magnesium is a solid metal, and chlorine is a diatomic gas.

### Step 2: Understand the Ionic Forms
In ionic form, magnesium exists as Mg²⁺, which means it has a +2 charge due to the loss of two electrons. Chlorine, on the other hand, exists as Cl⁻ ions when it gains an electron. Each chlorine atom has a valency of 1.
