Vedclass · Answer

(A) The electronic configuration follows the order of shells: $K=2, L=8, M=18, N=32$.Given that the $M$ shell has $13$ electrons and the $N$ shell has $1$ electron,the configuration is $1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^5, 4s^1$.This corresponds to the element $Cr$ (Chromium).In the $3d$ subshell,there are $5$ unpaired electrons,and in the $4s$ subshell,there is $1$ unpaired electron.Therefore,the total number of unpaired electrons is $5 + 1 = 6$.

If an atom has $13$ electrons in the $M$ shell and $1$ electron in the $N$ shell,then the number of unpaired electrons in that atom is ...
