- Lithium: 1 valence electron, represented as Li with one dot.
- Beryllium: 2 valence electrons, represented as Be with two dots.
- Nitrogen: 5 valence electrons, represented as N with five dots (one on each side and one paired).
- Fluorine: 7 valence electrons, represented as F with seven dots (three pairs and one single).
- Silicon: 4 valence electrons, represented as Si with four dots (one on each side).
- Neon: 8 valence electrons, represented as Ne with eight dots (four pairs).
- Sodium: 1 valence electron, loses 1 to achieve stability, forms Na⁺ ion.
- Oxygen: 6 valence electrons, gains 2 to achieve stability, forms O²⁻ ion.
- Aluminum: 3 valence electrons, loses 3 to achieve stability, forms Al³⁺ ion.
- Helium: 2 valence electrons, already stable (full first shell), does not form an ion.
- Potassium: 1 valence electron, loses 1 to achieve stability, forms K⁺ ion.
- Carbon: 4 valence electrons, typically shares electrons to form covalent bonds rather than gaining or losing 4 to form an ion.
