- Hydrogen: Group 1, 1 valence electron, Lewis structure: H with one dot, loses 1 electron
- Beryllium: Group 2, 2 valence electrons, Lewis structure: Be with two dots, loses 2 electrons
- Boron: Group 13, 3 valence electrons, Lewis structure: B with three dots, loses 3 electrons
- Nitrogen: Group 15, 5 valence electrons, Lewis structure: N with five dots, gains 3 electrons
- Oxygen: Group 16, 6 valence electrons, Lewis structure: O with six dots, gains 2 electrons
- Chlorine: Group 17, 7 valence electrons, Lewis structure: Cl with seven dots, gains 1 electron
- Calcium: Group 2, 2 valence electrons, Lewis structure: Ca with two dots, loses 2 electrons
- Aluminum: Group 13, 3 valence electrons, Lewis structure: Al with three dots, loses 3 electrons
- Bromine: Group 17, 7 valence electrons, Lewis structure: Br with seven dots, gains 1 electron
- Sulfur: Group 16, 6 valence electrons, Lewis structure: S with six dots, gains 2 electrons
Parent Tip: Review the logic above to help your child master the concept of valence electrons worksheet.
