Answer: Be is alkaline earth metal. Due to very small in size Be react with nitrogen to form covalent bond between them. Except Be other elements of same group form ionic bond with N2 so due to formation of covalent bond with nitrogen Be3N2 is volatile in nature.

And in case of gr 2 elements the solubility is also dec down the group due to hydration enthalpy so other elements are solid .

(Note* Be is amphoteric in nature)

Two vertical metallic plates carrying equal and opposite charges are kept parallel to each other like a parallel plate capacitor. A small spherical metallic ball is suspended by a long insulated thread such that it hangs freely in the centre of the two metallic plates. The ball, which is uncharged, is taken slowly towards the positively charged plate and is made to touch that plate. Then the ball...
