The Lewis symbol is a representation of an atom that shows its valence electrons as dots around the atomic symbol. Here are the Lewis symbols for each of the specified atoms:
- Chlorine (Cl): Chlorine has 7 valence electrons. The Lewis symbol is represented as: Cl: • • • • • • •
- Rubidium (Rb): Rubidium has 1 valence electron. The Lewis symbol is: Rb: •
- Phosphorus (P): Phosphorus has 5 valence electrons. The Lewis symbol is: P: • • • • •
- Aluminum (Al): Aluminum has 3 valence electrons. The Lewis symbol is: Al: • • •
These symbols are useful for understanding how atoms bond with one another, as the dots represent the electrons that can be involved in chemical bonding.
