What is the formula of the compound formed when magnesium reacts with oxygen?

Step 1: Identify the elements involved in the reaction. Here, we have magnesium (Mg) and oxygen (O).
Step 2: Determine the charge of magnesium. Magnesium typically has a charge of +2.
Step 3: Determine the charge of oxygen. Oxygen typically has a charge of -2.
Step 4: Combine the charges to form a neutral compound. To balance the +2 charge from magnesium, we need one oxygen with a -2 charge.
Step 5: Write the formula using the symbols for magnesium and oxygen. Since we need one magnesium and one oxygen, the formula is MgO.
