List of top Chemistry Questions on The Lanthanoids asked in NEET (UG)

ચાર અનપેર્ડ ઇલેક્ટ્રોનવાળો લેન્થેનાઇડ આયન છે (આપેલ છે: Ce = 58, Nd = 60, Tb = 65 અને Ho = 67):

The lanthanide ion having four unpaired electrons is
(Given : Atomic numbers of Ce = 58, Nd = 60, Tb = 65 and Ho = 67)

Although \(+3\) oxidation state is most common in lanthanoids, cerium still shows \(+4\) oxidation state because:

The incorrect statement among the following is :

Reason of lanthanoid contraction is

Which of the following lanthanoid ions is diamagnetic ?
(At. nos. Ce = 58, Sm = 62, Eu = 63, Yb = 70)

The correct order of ionic radii of $Y ^{3+}, La ^{3+}$ $Eu ^{3+}$, and $Lu ^{3+}$ is : - Atomic nos. $Y =39,\, La =57,\, Eu =63,\, Lu =71$.
