Question
Which metal is NOT an alkaline earth metal?
- Be
- Mg
- Sr
- 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.
