The chemistry of the actinoid elements is not so smooth as that of the lanthanoid. Justify this statement by giving some example from the oxidation state of these elements

Text Solution

Verified by Experts

Lanthanoids show limited number of oxidation state, viz., `+2, +3, ` and `+4` ( out of which `+3` is most common.) This is because of large energy gap between 4f and 5 d subshells. The dominant oxidation state of actinoids is also `+3` but they show a number of ther oidation states also, e.g., uranium `(Z = 92)` and plutonium `( Z= 94)` , show `+ 3, + 4, + 5 ` and `+6` , nuptunium `(Z = 94)` shows `+ 3, +4 , +5` and `+7` etc. This is due to small energy difference between 5f , 6d and 7s subshells of the actinoids.
