The difference of lithium from the other alkali metals is mainly because of:
Correct answer: D. Small radius and high charge density
- A. Large radius and low charge density
- B. Small radius and low charge density
- C. Large radius and high charge density
- D. Small radius and high charge density
Explanation
Correct, as lithium has the smallest atomic size in the alkali metal group, leading to high charge density, which makes it behave differently from other alkali metals (e.g., stronger covalent character in compounds and diagonal relationship with magnesium).

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.
