Solution
Alkaline earth metals have valency 2. This means that their position in the modern periodic table is in Group 2.
Explanation:
Alkaline Earth Metals include Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra). These elements have valency 2 because they have two electrons in their outermost shell (s-orbital). In the Modern Periodic Table, elements are arranged in groups and periods based on their electronic configuration. All Alkaline Earth Metals belong to Group 2.
