Interpret non-linear shape of `H_(2)S` and non-planar shape of `PCl_(3)` on the basis of VSEPR theory.

Explanation

To interpret the non-linear shape of H₂S and the non-planar shape of PCl₃ based on VSEPR theory, we will analyze the molecular geometry of both compounds step by step.

### Step 1: Determine the Valence Electrons
- **H₂S**: Sulfur (S) is in group 16 and has 6 valence electrons. Each hydrogen (H) has 1 valence electron. Therefore, the total number of valence electrons in H₂S is:
\[ 6 \, (\text{from S}) + 1 \times 2 \, (\text{from 2 H}) = 8 \, \text{valence electrons} \]
