(B) The electronic configurations of the given elements are:$Be (Z=4): 1s^2 2s^2$$Mg (Z=12): 1s^2 2s^2 2p^6 3s^2$$Ca (Z=20): 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2$All these elements belong to Group $2$ (alkaline earth metals) and have a valence shell configuration of $ns^2$.They do not contain $p$-electrons in their outermost energy level (valence shell). Therefore,option $B$ is not a similar characteristic.

Which is not a similar characteristic about the electronic configuration of $Be, Mg, Ca$?
