The incorrect statement about the lanthanoids is
P
(1) Their hardness increases with increase in
W atomic number.
(2) Lanthanoids having \( \mathrm{f}^{7} \) configuration are diamagnetic due to half-filled condition.
(3) Neodymium has maximum paramagnetism.
(4) The ionic character of Lanthanoid hydroxides decreases as the atomic no. of lanthanoid element increases.
