The alkali metals group lies in the _.
Correct answer: B. s-block
- A. d-block
- B. s-block
- C. f-block
- D. p-block
Explanation
The s-block in the periodic table of elements occupies the alkali metals and alkaline earth metals, also known as groups 1 and 2. Helium is also part of the s-block. The principal quantum number "n" fills the s orbital. There is a maximum of two electrons that can occupy the s orbital. A) d-block, C) f-block, and D) p-block are not the correct answers as the d-block consists of transition metals, the f-block consists of inner transition metals, and the p-block includes non-metals, metalloids, and some metals.

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.
