Explanation

Alkaline earth: Alkaline earths are the oxide of alkaline earth metals, namely lime, magnesia, strontia, baryta and beryllia. The alkaline earth metals are among the most electropositive of all metals, second only to the Group 1 or Alkali metals. Consequently, most of their compounds have a high degree of ionic character. This confers a high degree of basic nature to the oxides. On reacting with water, the corresponding hydroxides are obtained which are strong bases. Although highly corrosive, they are used as antacids for their strongly basic nature.
