Discuss the shape of the following molecules using the VSEPR model `: BeCl_2 ,BCl_3`

Explanation

To discuss the shapes of the molecules BeCl₂ and BCl₃ using the VSEPR (Valence Shell Electron Pair Repulsion) model, we will follow these steps:

### Step 1: Determine the Valence Electrons
- **BeCl₂**: Beryllium (Be) has 2 valence electrons, and each chlorine (Cl) has 7 valence electrons. Since there are two Cl atoms, the total number of valence electrons in BeCl₂ is:
\[ 2 + (2 \times 7) = 16 \text{ valence electrons} \]
