Assertion : Alkaline earth metals have lower densities than alkali metals. Reason : Atomic radii of alkaline earth metals are smaller than that of corresponding alkali metals.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:

CHXI10:THE S-BLOCK ELEMENTS
315882
The melting and boiling points of alkali metals decrease with the rise in atomic number due to weakening of
1 covalent bonding
2 ionic bonding
3 van der Waal's attraction
4 metallic bonding
Explanation:
As the size increases, the metallic bonding decreases.
