Verified step by step guidance1
Understand that the periodic table is organized into groups (columns) and periods (rows), where elements in the same group share similar chemical properties.
Recall that alkaline earth metals are a specific family of elements known for having two electrons in their outermost shell, which influences their chemical behavior.
Identify that Group 1 contains alkali metals, which have one valence electron, and Group 17 contains halogens, which have seven valence electrons.
Recognize that Group 18 contains noble gases, which are inert and have full valence shells.
Conclude that the alkaline earth metals are located in Group 2, characterized by having two valence electrons and including elements like magnesium and calcium.
