Which of the following statements is not true for lithium ?

→ Due to its small size, it has greater inter atomic attractions and hence "Li" is hardest metal in the IA group.→ Li easily reacts with atmospheric nitrogen and forms Li3N,Where as remaining elements of the same group they can't form nitrides at room temperature.→ Li in aqueous solution acts as strongest reducing agent among all metalsReasonThe hydration energy of Li+ is greater than the of sum of Ionisation and sublimation energies, as a result of this the lithium  ELiLi+o  electrode potential is very high + 3.04voltsLis→+SELig Lig→+IELig+ Lig++nH2O→-HELi+H2OnHE > [S.E + I.E]→ Due to  [Li] small size and high polarising power of Li+ ion, its compounds possess greater covalent character Polarising power∝Covalent character∝1Size of ionNote : The ability of a cation to cause distrotion in anion is called polarising power.
