Answer the following questions on the basis of the figure given below :
The electronic configuration of Ce is : 58Ce = [Xe]54 4f1 5d1 6s2 Calculate the spin only magnetic moment of Ce3+ ion.
Why is copper regarded as a transition element although copper atom has completely filled d-orbitals in its ground state ?
Why is Sc3+ colourless in aqueous solution whereas Ti3+ is coloured ?
Account for the following: (1) Transition metals form complex compounds. (2) The E°(Mn²⁺/Mn) value for manganese is highly negative whereas E°(Mn³⁺/Mn²⁺) is highly positive. (3) Cu⁺ ion is unstable in aqueous solution.
