Question

Explain why the ground state electron configuration of Ru is [Kr] 5s1 4d7 rather than [Kr] 5s2 4d6.

Answer 1

same electronic Also ground state electronic configuration of rather than Ru is [kr] sog' ud7 [kr] means that the 'r Core [ko]562 udb because Orbital & have the ac as kopton does configuration the eight extra election are distributed , seven in ad orbitals and a in the 5s orbital . . The hydrogen like orbital model takes both orbital energies and overall election interaction energies into account and in the case of Ra having the 58 singly occupied, with r electron in 4d subshell has lower overall energy than having 58 doubly occupied and six electron in the fd but we normally think of the 5s as being lower in energy than the 4d - it is occupied fost but difference is the energy rather small and can be overridden by Puterachion factors” 66 electron no
