Sodium and potassium react with water much more vigorously than lithium because `:`

Options

A. sodium and potassium have high values of hydration energy as compared to that of lithium.
B. sodium and potassium have higher melting point than that of lithium.
C. sodium and potassium have lower melting point than that of lithium.
D. sodium and potassium have lower hydration energy htan that of lithium.

Answer

3

Explanation

When sodium and potassium react with water, the heat evolved causes them to meld, giving a larger area of contact with water, lithium on the other hand, does not melt under these condition and thus reacts more slowly.
Melting point `(.^(@)C)` `{:(Li,Na,Na,),(180,98,64,):}`
