In alkali metals the highest shielding effect is exhibited by:
Correct answer: D. Rb
- A. Li
- B. Na
- C. K
- D. Rb

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.
