Verified step by step guidance1
Recall the definition of alkaline earth metals: they are elements found in Group 2 of the periodic table, characterized by having two electrons in their outermost shell.
Identify the given elements and their positions in the periodic table: Fe (iron) is a transition metal, Na (sodium) is an alkali metal in Group 1, Mg (magnesium) is in Group 2, and Cl (chlorine) is a halogen in Group 17.
Since alkaline earth metals are specifically Group 2 elements, focus on the element that belongs to this group.
Recognize that Mg (magnesium) is the only element among the options that is in Group 2, making it an alkaline earth metal.
Conclude that Mg is the correct answer because it fits the criteria of an alkaline earth metal based on its group placement in the periodic table.
