Melting point of Group I-A elements is _ than Group II-A elements
Correct answer: B. Lower
- A. Higher
- B. Lower
- C. Same
- D. Varies
Explanation
The melting point of Group I-A elements is lower than Group II-A elements. This is because the Group I-A elements have weaker metallic bonding due to the presence of a single valence electron, which is easily lost. In contrast, Group II-A elements have two valence electrons, leading to stronger metallic bonding and higher melting points.

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.
