Explain the following - (a) Melting point of Fe is higher than that of Cu. (b) Magnetic moment of Ni^(2+) is lower than that of Co^(2+). (c ) Scandium does not produce coloured ions but still it is a transition element. (d) The increasing order of oxidation states of the oxo - ions is : VO_(2)^(+)lt CrO_(7)^(2-)lt MnO_(4)^(-) |
| Answer» SOLUTION :(a) N/A(b) N/A (C ) Sc ghas partially filled d - orbitals in its penultimate SHELL but `Sc^(3+)` has no d - electron and thus d - d transition is not possible (d) N/A | |
