Densities of alkali metals are low due to:
Correct answer: B. Large atomic volume
- A. Weak intermolecular forces
- B. Large atomic volume
- C. Smaller size
- D. ns1 configuration
Explanation
The alkali metals have the largest atomic volume due to less no of protons in their nucleus. Density is inversely proportional to volume, so the greater the volume, the less dense the metal would be.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
