Vedclass · Answer

(B) The atomic number of cobalt $(Co)$ is $27$. Following the Aufbau principle,the electrons are filled in the order of increasing energy levels: $1s, 2s, 2p, 3s, 3p, 4s, 3d$. The distribution of $27$ electrons is: $1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^7$. Thus,the correct electronic configuration is $1s^2, 2s^2 2p^6, 3s^2 3p^6 3d^7, 4s^2$.

The electronic configuration of cobalt ($Co$,atomic number $27$) is:
