In certain matters, lithium differs from other alkali metals, the main reason for this is :
A
Small size of lithium atom and Li+ ion
B
Extremely high electropositivity of Li
C
Greater hardness of Li
D
Hydration of Li+ ion
Answer
Small size of lithium atom and Li+ ion
Explanation
Solution
It has highest polarising power among the alkali metals because of small size and thus show different properties than that of other elements of the group.
