Silver atom has completely filled d-orbitals in its ground state, it is still considered to be a transition element. Justify the statement.
Why do transition metals form alloys ?
Why are E°M2+/M values of Mn and Zn more negative than expected ?
Account for the following: (i) E° value for Mn³⁺/ Mn²⁺ couple is much more positive than that for Cr³⁺/ Cr²⁺. (ii) Sc³⁺ is colourless whereas Ti³⁺ is coloured in an aqueous solution. (iii) Actinoids show wide range of oxidation states.
Write the chemical equations for the preparation of KMnO₄ from MnO₂.
Account for the following: (i) Transition metals form alloys. (ii) Ce⁴⁺ is a strong oxidising agent.
