Question

Basic order for oxides of group 2 elements

Answer 1

Explanation:

on going down the group in alkaline earth metals and alkali metals, as the atomic size increases, the reactivity increases. Hence on going down the group, the basic character of oxides also increases:

MgO < SrO < K

2

O < Cs

2

O

Answer 2

Answer:

on going down the group in alkaline earth metals and alkali metals, as the atomic size increases, the reactivity increases. Hence on going down the group, the basic character of oxides also increases: MgO < SrO < K2O < Cs2O
