The electrons in a poly -electronic atom are filled one by one in roder fo increasing energy level . The enrgy fo subsgells and orientation depeds upon the values of three quantum numbers 9 i.e., n. l and m respectively derived from Schrodinger wave equation . The different orbitals fo a subsshells however possess same energy level and are called degenerater orbitals but their enrgy level charges in presenct fo magentic field and the orbitals are non-degenerate . (A) spectral line is noticed it an electron jups form one level to tohere . the paramgnetic nature of eelment sis due to the presence of unpaired electron . Which is each pair is most stable ion? ` Cu^+` or ` Cu^(2+) ` and ` Fe^(2+)` or ` Fe^(=)` .A. `Cu^+ , Fe^(3+)`B. `Cu^(2+) , Fe^(3+)`C. `Cu^(2+) , Fe^(3+)`D. `Cu^+ , Fe^(3+)` |

Answer» Correct Answer - B `Cu^+ (3d^(10))` shows disproprotionation and thus less stable than ` cu^(2+)`. |
