Write Lewis symbols for the following atoms and ions : S and `S^(2-), Al and Al^(3+)`. H and `H^(-)`.

Explanation

To write the Lewis symbols for the given atoms and ions, we will follow these steps:

### Step 1: Write the Lewis symbol for Sulfur (S)
- **Atomic Number**: 16
- **Electronic Configuration**: 1s² 2s² 2p⁶ 3s² 3p⁴
- **Valence Electrons**: 6 (from the 3s and 3p orbitals)
- **Lewis Symbol**: Represent the 6 valence electrons as dots around the symbol for sulfur (S). The arrangement will show 2 electrons in the 3s orbital and 4 electrons in the 3p orbital.
