Choose the correct statements from the following:

1.	Choose the correct statements from the following:
Answer» Beryllium is not readily attacked by acids because of the PRESENCE of an oxide film on the surface of the METAL. Beryllium sulphate is readily soluble in water as the greater hydration enthalpy of `Be^(2+)` overcomes the lattice enthalpy factor. Beryllium EXHIBITS coordination number more than four. Beryllium oxide is purely acidic in nature. Solution :Be resembles Al (diagonal RELATION) and form protective film of oxide and not attacked readily by acids. `BeSO_(4)` is soluble in water due to highhydration enthalpy of `Be^(2+)`. LIKE `Al_(2)O_(3), BeO` is amphoteric in nature.
