Chemistry of actionoids is complicated as compared to lathanoids. Give reason

(a) (i) How is the variability in oxidation states of transition metals different from that of the p-block elements? (ii) Out of Cu^+ and Cu^(2+) , which ion is unstable in aqueous solution and why? (iii) Orange colour of Cr_2O_7^(2-) ion changes to yellow when treated with an alkali. Why? (b) Chemistry of actinoids is complicated as compared to lanthanoids. Give two reasons.

(a) How would you account for the following: (i) The chemistry of actinoids is more complicated as compared to lanthanoids. (ii) Transition metals form complex compounds. (b) Complete the following equation: 2MnO_4^(-) + 6H^(+) + 5SO_3^(2-) to

How will you account for the following : (a) (i) The chemistry of actnoids is more complicated as compared to lanthanoids . (ii) Transition metal from complex compounds. (b) Complete the following equations : 2MnO_(4)^(-)+6H^(+)+5SO_(3)^(2-) to

Assertion (A): Chemistry of Actinoids is more complicated than Lanthanoids Assertion (R): Actionid elements are radio active

The chemistry of the early actinoids is more complicated than the corresponding lanthanoids
