Give two reasons the chemistry of actinoids is more complicated than Lanthnoids.

Explain giving reasons : (i) Transition metals and their compounds generally exhibit a paramagnetic behaviour. (ii) The chemistry of actinoids is not so smooth as that of lanthanoids.

Give any 2 general characteristics of actinoids.

Give reason.the radius of anion is always greater than neutral atom.

Give reason: Why Lanthanoids are less reactive than actinoids.

Give reason: Actinoid contraction is greater from element to element than lanthanoid contraction.

What is actinoid contraction? Why actinoid contraction is greater than lanthanoid contraction?

Give two reasons for the appearance of variations among the progeny formed by sexual reproduction
