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 discuss the shape of the given molecules using the VSEPR (Valence Shell Electron Pair Repulsion) model, we will analyze each molecule step by step:

### 1. **BeCl₂ (Beryllium Chloride)**
- **Valence Electrons**: Beryllium has 2 valence electrons and each chlorine has 7 valence electrons.
- **Bond Formation**: Beryllium shares one electron with each of the two chlorine atoms, forming two Be-Cl single bonds.
- **Steric Number Calculation**:
- Number of sigma bonds = 2 (Be-Cl bonds)
- Number of lone pairs on Be = 0
