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.
