Odisha Board Solutions for Chapter: The f-block Elements, Exercise 1: QUESTIONS

Compare the chemistry of actinoids with that of lanthanoids with special reference to electronic configuration.

Compare the chemistry of actinoids with that of lanthanoids with special reference to atomic and ionic radii.

Compare the chemistry of actinoids with that of lanthanoids with special reference to oxidation states.

Name an important alloy containing some of the lanthanoid metals. Mention its uses.

Which is the last element in the series of Actinoids? Write its electronic configuration.

$\mathrm{La}{\left(\mathrm{OH}\right)}_3$ is more basic than $\mathrm{Lu}{\left(\mathrm{OH}\right)}_3$, why’?

Why ${\mathrm{Sm}}^{2+}, {\mathrm{Eu}}^{2+}$and ${\mathrm{Yb}}^{2+}$ ions in solutions are good reducing agents, but an aqueous solution of ${\mathrm{Ce}}^{4+}$ is a good oxidising agent.

Compare the chemistry of actinoids with that of lanthanoids with special reference to chemical reactivity.
