Verified Answer :

GinnyAnswer

Final answer:

Magnesium's electronic configuration is similar to calcium, but their total number of electrons differs. Understanding electronic configurations aids in predicting reactivity and ion formation.


Explanation:

Magnesium's electronic configuration of [Ne]3s² is similar to calcium's electronic configuration of [Ar]4s². Both have filled s subshells outside their filled inner shells.

However, magnesium has 12 electrons while calcium has 20 electrons, making their overall electronic configurations different.

Understanding electronic configurations helps predict chemical reactivity and ion formation in elements.
