Question

N0. The atomic radli of alkali metals (M) lie in the order Li < Na <K
< Rb but the radii of M+ ions in aqueous solution lie in the
reverse order Li-> Nat> K+ > Rb*. What is the reason for this
reverse order (on going from Lito Rb)?
(a) Gradual increase in ionization enthalpy
(b) Increasing weakness of the metallic bond
(c) Increasing electropositive character
(d) Decreasing degree of hydration​

Answer 1

Answer:

option b is corect gradualy increase weekness of the metalic bond
