1.	Name an element from group 2 which forms an amphoteric oxide and a water soluble sulphate.
Answer» Due to small size and somewhat high ionization enthalpy of Be , `Be(OH)_(2)` is amphoteric in nature , i.e., it reacts with both acids and base . Further due to small size , the hydration enthalpy of `Be^(2+)` ions is much higher than the lattice enthalpy of `BeSO_(4)` . As a result , `BeSO_(4)` is highly soluble in water .

A Typical characteristic of the representative element is that the first member of each group gives different present in that group. Lithium is no excepton. Through it is the first member of the alkali metal family (group f), it is anomalous in behaviour. This may be attributed to the small size of both Li and `Li^(+)` ion, high ionisation enthalpy, high polarising power, and non- availability of d-electrons in its valence shell.
