Write Lewis symbols for the following atoms and ions: $S$ and $S^{2-}$,$Al$ and $Al^{3+}$,$H$ and $H^{+}$.

(N/A) Lewis symbols represent the valence electrons of an atom or ion as dots around the chemical symbol.
$1$. For $S$ and $S^{2-}$:
- $S$ (atomic number $16$): Valence shell configuration is $3s^2 3p^4$. It has $6$ valence electrons. Lewis symbol: $\cdot \cdot \ddot{S} \cdot \cdot$
- $S^{2-}$: Gains $2$ electrons to complete the octet. Lewis symbol: $[ \cdot \cdot \ddot{\underset{\cdot \cdot}{S}} \cdot \cdot ]^{2-}$
$2$. For $Al$ and $Al^{3+}$:
- $Al$ (atomic number $13$): Valence shell configuration is $3s^2 3p^1$. It has $3$ valence electrons. Lewis symbol: $\cdot \dot{Al} \cdot$
- $Al^{3+}$: Loses $3$ electrons. Lewis symbol: $[Al]^{3+}$
$3$. For $H$ and $H^{+}$:
- $H$ (atomic number $1$): Has $1$ valence electron. Lewis symbol: $H \cdot$
- $H^{+}$: Loses $1$ electron. Lewis symbol: $H^{+}$
