Write formulase for the following compounds :
Mg(II) chloride

Answer

To write the formula for magnesium(II) chloride, we need to follow these steps:

### Step 1: Identify the elements involved
The compound is magnesium(II) chloride, which consists of magnesium (Mg) and chlorine (Cl).

### Step 2: Determine the oxidation states
- Magnesium (Mg) typically has an oxidation state of +2 in its ionic form (Mg²⁺).
- Chlorine (Cl) typically has an oxidation state of -1 in its ionic form (Cl⁻).

### Step 3: Balance the charges
To form a neutral compound, the total positive charge must equal the total negative charge. Since magnesium has a +2 charge, we need two chloride ions to balance this charge:
- 1 Mg²⁺ ion contributes +2 charge.
- 2 Cl⁻ ions contribute -2 charge (2 × -1).

### Step 4: Write the formula
Combining the ions, we get:
- 1 magnesium ion (Mg²⁺) and 2 chloride ions (Cl⁻).
Thus, the formula for magnesium(II) chloride is MgCl₂.

### Final Answer:
The formula for magnesium(II) chloride is **MgCl₂**.
