Question

In certain matters lithium differs from other alkali metals, the main reason for this is.

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

Answer 1

Answer: (A)

Small size of Li atom and $Li^{+}$ ion

Answer 2

Small atomic and ionic size leads to high

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