Short Answer TypeWhy Sm2+, Eu2+ and Yb2+ ions in solutions are good reducing agents but an aqueous solution of Ce4+ is a good oxidizing agent?
One among the lanthanoids, Ce(III) can be easily oxidized to Ce(IV) (at. No. of Ce = 58). Explain why?
The +3 oxidation states of lanthanum (Z = 57), gadolinium (Z = 64) and lutetium (Z = 71) are especially stable. Why?
Which metal in the first series of transition metals exhibits +1 oxidation state most frequently and why?
Copper metal (Cu, at. no. 29) shows +1 oxidation state i.e., it exists as Cu+ in large number of copper compounds e.g., cuprous oxide (Cu2O), cuprous sulphide (Cu2S); cuprous chloride (Cu2Cl2) etc. The electronic configuration of Cu+ is [Ar] 3d10 4s0.
This configuration is very stable as all five 3d orbitals are fully filled.
Write the electronic configurations of the elements with the atomic numbers 61, 91, 101 and 109.
Write chemical equations for the reactions involved in the manufacture of perman-ganate from pyrolusite ore.
Why is the + 2 oxidation state of manganese quite stable while the same is not true for iron? |Mn = 25, Fe = 26]
