Question

Certain characteristics lithium differ from those of other alkali metals, the main reason for this is

• A. Small size of $Li$ atom and $L{i}^{+}$ ion
• B. Extremely high electropositivity of $Li$
• C. Greater hardness of $Li$
• D. Hydration of $L{i}^{+}$ ion

Answer 1

Answer: (A)

Small atomic and ionic size leads to high electronegativity and hydration energy. Small atomic and ionic size leads to high electronegativity and hydration energy
