Group 2 elements are known as what?

• A. Noble Gases
• B. Alkaline Earth Metals
• C. Halogens
• D. Transition Metals

Answer: (B)

Alkaline earth metals are the Group 2 elements. They occupy the second column of the periodic table and have two valence electrons, giving them a ns2 electron configuration. Because of this, they almost always form a +2 oxidation state in compounds. Their oxides are basic, and when dissolved in water they produce alkaline solutions, which is why they’re called alkaline earth metals. They’re metallic and fairly reactive, with reactivity increasing down the group. They belong to the s-block, distinguishing them from the noble gases, halogens, and transition metals. Examples include beryllium, magnesium, calcium, strontium, barium, and radium.
