Answer the following question: Answer the following question given this paragraph: The elements in Group 2 (beryllium, magnesium, calcium, strontium, barium, and radium) are called the alkaline earth metals (see Figure below ). These elements have two valence electrons, both of which reside in the outermost s sublevel. The general electron configuration of all alkaline earth metals is n s 2 . The alkaline earth metals are still too reactive to exist in nature as free elements, but they are less reactive than the alkali metals. They tend to be harder, stronger, and denser than the alkali metals, and they also form numerous compounds with nonmetals. Q: The elements in group 2 are called what? A:

Choices:
*halogens.
*metal alloys.
*noble gases.
*alkaline earth metals.
Answer:
alkaline earth metals
