A list shows four properties of beryllium, Be, or a beryllium compound. Which one of these properties is unlike the property of magnesium or the corresponding magnesium compound?
- ABe reacts with $\text{O}_2$ when heated in air; Mg does not.
- BBe reacts with aqueous $\text{H}_2\text{SO}_4$ to form a metal sulfate and $\text{H}_2$; Mg does not.
- C$\text{Be(NO}_3)_2$ decomposes on heating to form a metal oxide, $\text{NO}_2$ and $\text{O}_2$; $\text{Mg(NO}_3)_2$ does not.
- D$\text{BeCl}_2$ reacts with water to form fumes of HCl; $\text{MgCl}_2$ does not.
