The Periodic Table: chemical periodicity — practice question

Magnesium and sulfur each produce ions with a 2+ charge. How do the atomic radii and ionic radii of these two elements compare?

  • A$\text{Mg} > \text{Mg}^{2+}$ and $\text{S} > \text{S}^{2-}$
  • B$\text{Mg} > \text{Mg}^{2+}$ and $\text{S} < \text{S}^{2-}$
  • C$\text{Mg} < \text{Mg}^{2+}$ and $\text{S} > \text{S}^{2-}$
  • D$\text{Mg} < \text{Mg}^{2+}$ and $\text{S} < \text{S}^{2-}$
