Compare the chemistry of actinoids with that of lanthanoids with special reference to :
(i) Atomic sizes (ii) Chemical reactivity.

Text Solution

Verified by Experts

(i) Atomic Sizes. Actinoids show greater contraction in sizes as we the from left to right due to poorer shielding by 5f electrons than 4f electrons.
(ii) Chentical reactivity. They are more reactive than lanthanoids.
