Alkaline earth metals are very reactive but less than alkali metals. They have atoms that have two outer electrons. They have the color of silver and have higher densities than alkali metals.Elements in group two have many uses. Such as magnesium, magnesium can be mixed with other metals to make low-density materials. Group two have six elements. The six elements are Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
