Alkaline Earth Metal
Alkaline earth metals are the six elements in Group 2 of the periodic table: Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). They are shiny, silvery-white, moderately reactive metals known for forming basic (alkaline) solutions in water and having two valence electrons, which they readily lose to form +2 ions, making them important in ionic compounds.
