The reactivity of halogens decrease down the group but of alkali metals increases down the group. Why?

Select incorrect statement about alkaline earth metals: (A) Solubility of sulphates decreases down the group (B) Solubility of hydroxides decreases down the group (c) Thermal stability of carbonates increases down the group D) Basic nature increases down the group

A : Solubility of alkaline earth metal carbonates decreases down the group. R : Hydration enthalpy decreases down the group whereas lattice enthalpy remain almost constant

Ionisation energy decreases down the group due to

In group 16, the stability of + 6 oxidation state decreases and that of + 4 oxidation state increases down the group. Why ?

Why does ionization energy decreases down the group?

Assertion : Solubilities of alkali metal fluorides and carbonates increase down the group. Reason : Hydration energies of alkali metal halides decrease down the group with increase in size of cations.
