Which physical property in the alkali metal group increases with atomic number ?

A

Melting point

B

Electronegativity

C

Hydration enthalpy

D

Density

Text Solution

Verified by Experts

The correct Answer is:
D
Density of the alkali metals almost increases on moving down the group. However, a small decrease in density is observed from Na to K, due to abnormal increase in atomic size from Na to K.
