Vedclass · Answer

(A) The atomic number of Radon $(Rn)$ is $86$. For an element with atomic number $Z = 106$,the electronic configuration is filled as follows: $1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^{10}, 4p^6, 5s^2, 4d^{10}, 5p^6, 6s^2, 4f^{14}, 5d^{10}, 6p^6, 7s^2, 5f^{14}, 6d^4$. However,according to the stability rules for $d$-block elements,the configuration is $[Rn] \, 5f^{14} \, 6d^4 \, 7s^2$. Wait,checking the specific configuration for Seaborgium $(Z=106)$: The ground state configuration is $[Rn] \, 5f^{14} \, 6d^4 \, 7s^2$.

Elements after atomic number $103$ have been discovered. If an element with atomic number $106$ is considered,which of the following electronic configurations will it possess?
