Anomalous behavior of Lithium

The properties of Li and its compounds are differ
far more from those of the other Group 1 elements
1. Mp and bp of Li is much higher than those for
other Group 1 elements
2. Li is much harder than rest of the group
3. Li reacts with O2 least readily to form normal
oxide. Peroxide is formed with great difficulty.
Higher oxides are unstable
4. LiOH is less basic compared to that of other
elements in the same group, and many of its salts
are less table. Li2CO3, LiNO3 and LIOH forms oxide
with gentle heating whereas analogous compounds
of the group shows higher thermal stability
5. Li forms Li3N on heating with N2 but none of
other in the group does not
6. Li directly react with C to form ionic carbide, but
not others in the group
7. Li has greater tendency to form complexes
8. Li2CO3, Li3PO4, LiF are insoluble in water and
LiOH sparingly soluble, but the rest of group forms
water soluble compounds
9. The halides and alkyls of Li are far more
covalent in nature than that of Na compounds and
therefore they soluble in organic solvents.
10. The Li ion itself and also it’s compounds are
more heavily hydrated than those of the rest of the
group

Lithium compounds are widely used in treating bipolar disorder
although there are some side effects.
