d and f-Block ElementsHard

Question

Identify the incorrect statement among the following

Options

A.d-Block elements show irregular and erratic chemical properties among themselves
B.La and Lu have partially filled d orbitals and no other partially filled orbitals
C.The chemistry of various lanthanoids is very similar
D.4f and 5f orbitals are equally shielded

Solution

4f and 5f belongs to different energy levels, hence the shielding effect is on them is not the same.
Shielding of 4f is more than 5f.
Hence (4) is correct.
