    Question

    Which metal is NOT an alkaline earth metal? 

    1. Be
    2. Mg
    3. Sr
    4. Ba

    Hint:

    Be does not form basic hydroxides.

    The correct answer is: Be

      • Group 2 elements are called alkaline earth metals.
      • All the alkaline earth metals forms basic hydroxide with water.
      • But Be does not form basic hydroxides rather it shows amphoteric behavior.
      • Hence, Be is not alkaline earth metal.
