Discuss the shape of the following molecules using the `VSEPR` model:
`BeCl_(2)`,`BCl_(3)`,`SiCl_(4)`,`AsF_(5)`,`H_(2)S`,`PH_(3)`

Explanation

To determine the shapes of the given molecules using the VSEPR (Valence Shell Electron Pair Repulsion) model, we will analyze each molecule based on the number of valence electrons, bonding pairs, and lone pairs of electrons. Here’s a step-by-step breakdown for each molecule:

### 1. **BeCl₂ (Beryllium Chloride)**
- **Valence Electrons**: Beryllium has 2 valence electrons.
- **Bonding Pairs**: It forms 2 bonds with chlorine atoms.
- **Lone Pairs**: There are no lone pairs on beryllium.
- **Shape**: Since there are 2 bonding pairs and no lone pairs, the shape is **linear**.
