Which element has smaller shielding effect among the following?
Correct answer: A. Mg
- A. Mg
- B. Ca
- C. Rb
- D. Sr
Explanation
Magneisum has the smallest shielding effect in the given elements, because as you move alonga group(from top to bottom in the periodic table), the number of shells increases and effective nuclear charge decreases, leading to weaker attraction of electrons.

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.
