  • Explain the following observations : (i) Silver atom has completely filled d-orbitals (4d10) in its ground state, yet it is regarded as a transition element. (ii) E0 value for <img alt="Mn^{3+}/Mn^{2+}" sr

Explain the following observations :

(i) Silver atom has completely filled d-orbitals (4d10) in its ground state, yet it is regarded as a transition element.

(ii) E0 value for Mn^{3+}/Mn^{2+} couple is much more positive than Cr^{3+}/Cr^{2+} .

E^{0} value of Mn^{3+}/Mn^{2+} couple is much more positive than Cr^{3+}/Cr^{2+}since Mn^{2+} is more stable than Mn^{3+} because Mn^{2+} has the configuration 3d5 which is extra stable half filled configuration.
