The Periodic Table: chemical periodicity — practice question

An element, $Y$, takes part in the sequence shown below. When $Y$ burns in $\text{O}_2$, a white solid is formed. This white solid reacts with $\text{HCl(aq)}$ to produce a solution. When $\text{NaOH(aq)}$ is added, a white precipitate is formed, and this precipitate then dissolves in excess $\text{NaOH(aq)}$ to form a solution. Which element could $Y$ be?

  • A$\text{Na}$
  • B$\text{Mg}$
  • C$\text{Al}$
