- 3a: Atomic number(Z) = 9
- 3b: Atomic number(Z) = 17
- 3c: Atomic number(Z) = 35
- 3d: Atomic number(Z) = 53
- 4a: Number of Protons = 9, Number of electrons = 10
- 4b: Element = Iodine, Ion symbol = I⁻, Ion type = Anion
- 4c: Element = Sulfur, Ion symbol = S²⁻, Number of Protons = 16, Ion type = Anion
- 4d: Ion symbol = K⁺, Number of Protons = 19, Number of electrons = 18, Ion type = Cation
- 4e: Ion symbol = Ca²⁺, Number of Protons = 20, Number of electrons = 18, Charge = +2, Ion type = Cation
