Draw the structure of :
`SO_(3)^(2-)`

Explanation

To draw the structure of \( SO_3^{2-} \), we will follow these steps:

### Step 1: Determine the Valence Electrons
Sulfur (S) has an atomic number of 16, and its electron configuration is \( 1s^2 2s^2 2p^6 3s^2 3p^4 \). The valence electrons for sulfur are in the 3rd shell: 2 from 3s and 4 from 3p, totaling 6 valence electrons. Each oxygen (O) has 6 valence electrons, and since there are 3 oxygen atoms, that contributes \( 3 \times 6 = 18 \) valence electrons. The \( 2- \) charge indicates that we have 2 additional electrons, giving us a total of:

\[ 6 \text{ (from S)} + 18 \text{ (from 3 O)} + 2 \text{ (from charge)} = 26 \text{ valence electrons} \]
