Give the name and atomic number of the inert gas atom in which the total number of `d`-electrons is equal to the difference in number to the `p`-and `-s`-electrons. |

Answer» Correct Answer - 36 First gas which contains d-electron is Kr `implies 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6` Total number of d-electrons =10 `implies` Total number of p-electrons =6+6+6=18 Total number of s-electrons =2+2+2+2=8 Difference in total number of p- and s- electrons =18-8=10 So inert gas is `._35` Kr. |
