Question
In the stable ionic state formed by alkaline earth metals ($M^{2+}$), what is the number of electrons present in the outermost $s$ subshell?
Answer: 0
💡 Solution & Explanation
Alkaline earth metals have the general configuration $ns^2$. They lose these two valence electrons to form stable $M^{2+}$ ions. Therefore, 0 electrons remain in the outermost $s$ subshell.
