Transuranium elements are

Determine whether the following statements are True $(T)$ or False $(F)$:
$(a)$ Actinoid contraction increases from one element to the next.
$(b)$ Actinoid contraction decreases from one element to the next.
$(c)$ Lanthanoid contraction occurs,but actinoid contraction does not occur.

Name the members of the lanthanoid series which exhibit $+4$ oxidation state and those which exhibit $+2$ oxidation state. Try to correlate this type of behavior with the electronic configurations of these elements.

The lanthanide contraction is responsible for the fact that

Which of the following properties of lanthanoids is $NOT$ true?

Which lanthanoid from the following may exhibit $+4$ oxidation state with $f^{0}$ configuration?
