To balance the chemical equation \( \text{Mg} + \text{O}_2 \rightarrow \text{MgO} \), you need to ensure that there are equal numbers of each type of atom on both sides of the equation.

1. On the left side, you have 2 oxygen atoms in \( \text{O}_2 \).
2. On the right side, each \( \text{MgO} \) has 1 oxygen atom.

To balance the oxygen, you will need 2 \( \text{MgO} \) on the right side:

\[ \text{Mg} + \text{O}_2 \rightarrow 2 \text{MgO} \]

Now, with 2 \( \text{MgO} \), you have 2 magnesium (Mg) atoms on the right side, so you will need 2 magnesium atoms on the left side as well:

\[ 2 \text{Mg} + \text{O}_2 \rightarrow 2 \text{MgO} \]

Now the balanced equation is:

\[ \text{Balanced equation: } 2 \text{Mg} + \text{O}_2 \rightarrow 2 \text{MgO} \]

Therefore, the filled blanks are as follows:

Blank 1: 2 (for Mg)
Blank 2: 1 (for O2)
Blank 3: 2 (for MgO)
