B. Beryllium carbonate is kept in the atmosphere of $CO_2$ because it is thermally less stable.

C. Beryllium sulphate is readily soluble in water due to high degree of hydration.

D. Beryllium shows anomalous behaviour due to small size, high ionization energy and high value of $\phi$ (polarising power).
