Give bond angles in `H_(2)O, CH_(4) and SF_(6)` molecules.

Explanation

To determine the bond angles in the molecules H₂O (water), CH₄ (methane), and SF₆ (sulfur hexafluoride), we will analyze each molecule step by step.

### Step 1: Analyze H₂O (Water)
1. **Count Valence Electrons**: Oxygen (O) has 6 valence electrons, and each hydrogen (H) has 1 valence electron. Therefore, for H₂O:
- Total valence electrons = 6 (O) + 1 (H) + 1 (H) = 8 electrons.

2. **Determine Hybridization**:
- Use the formula: (Number of valence electrons on central atom + Number of monovalent atoms) / 2.
