The Periodic Table: chemical periodicity — practice question

For reactions 1 and 2, X stands for an element in Period 3. In both reactions, X is being converted into a product in which X has its maximum oxidation state. reaction 1: chlorine + element X $\rightarrow X_y\text{Cl}_z$ reaction 2: oxygen + element X $\rightarrow X_p\text{O}_q$ Which ratios increase progressively from sodium to phosphorus?

  • Aneither $z:y$ nor $q:p$
  • B$z:y$ only
  • C$q:p$ only
  • Dboth $z:y$ and $q:p$
