Which of the following lists correctly represents the elements in Group 2, the alkaline earth metals?

Explanation:
Group 2 elements are the alkaline earth metals, found in the second column of the periodic table. They all have two valence electrons, giving them a +2 oxidation state, and they are reactive metals located in the s-block. The list that includes Be, Mg, Ca, Sr, Ba, and Ra matches exactly these elements, from beryllium up to radium. The other lists mix elements that aren’t in Group 2: some are nonmetals, some are noble gases, and one lists alkali metals in Group 1.
