1.	Atomic radii of alkaline earth metals are smaller than the corresponding members of alkali metals. Why?
Answer» Solution :The atomic RADII of alkaline earth metals are smaller than alkali metals. This is due to the fact that group 2 elements have a higher NUCLEAR charge, allowing the electrons to move TOWARDS the nucleus. This reduces the size of atomic and IONIC radii.
