Question

Which alkaline earth metal do not crystallize water molecule?

Answer 1

First of all remember that alkaline earth metals have greater charge density as compared to alkali metal so more charge is present Mg+2 then Na+1 .Because of greater charge is present in alkaline earth metals so having great ability to attract water molecule and form a salt .

Now considered that down the group the size of element increase so charge also increase so in the 2nd group of alkaline earth metals the ( Be) size is lower as compare to others.
