Choose the correct statement(s) (A) Beryllium oxide is purely acidic in nature. (B) Beryllium carbonate is kept in the atmosphere of CO2. (C) Beryllium sulphate is readily soluble in water. (D) Beryllium shows anomalous behaviour. Choose the correct answer from the options below :

1. (1) A, B & C only
2. (2) A only
3. (3) A and B only
4. (4) B, C and D only

Correct answer: (4) B, C and D only

Solution

Beryllium carbonate is indeed kept in an atmosphere of CO2 to prevent its decomposition, beryllium sulfate is known for its high solubility in water, and beryllium exhibits anomalous behavior compared to other alkaline earth metals due to its unique properties. Therefore, options B, C, and D are correct.
