Sulfur versus calcium? Chalk versus cheese?

Explanation:

Sulfur is a fairly unreactive non-metal that has almost NO solubility in water. Sulfur CAN be oxidized to give reactive gases, that are acid anhydrides.

On the other hand, calcium is a fairly reactive alkaline earth metal that will react with water to give dihydrogen gas and calcium hydroxide. You realize that I am not really answering your question, because it is difficult to assess reactivity reasonably.
