C. Beryllium sulphate is readily soluble in water.
D. Beryllium shows anomalous behavior.
Choose the correct answer from the options given below:

• A. A, B and C only
• B. B, C and D only
• C. A and B only
• D. A only

Answer 1

Answer: (B)

A. Beryllium oxide is amphoteric in nature.
B. Beryllium carbonate is kept in the atmosphere of $C{O}_2$ 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 $\varphi$ (polarising power).
