On moving down the group in metals, reactivity of metals
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remain unchanged
- D. Has irregular trend
Explanation
(Increases) - Correct: Down the group, metallic reactivity increases because atomic size increases, and ionization energy decreases, making electron loss easier.

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.
