$Ca^{2+}$

Vedclass · Answer

(D) The electronic configuration of neutral calcium ($Ca$,atomic number $20$) is $2, 8, 8, 2$.When it forms the $Ca^{2+}$ ion,it loses $2$ electrons from the outermost shell.The electronic configuration of $Ca^{2+}$ becomes $2, 8, 8$.In $Ca^{2+}$,the outermost shell (third shell) has $8$ electrons,and the penultimate shell (second shell) also has $8$ electrons.Therefore,$Ca^{2+}$ is the species that has the same number of electrons in its outermost and penultimate shells.

Which among the following species has the same number of electrons in its outermost as well as penultimate shell?
