Question

How many s-block and p-block elements are there in the second period of the modern periodic table ?

• A. 2, 8
• B. 8, 2
• C. 2, 6
• D. 4, 8

Answer 1

The Correct Option is C

To solve this question, we need to determine the number of s-block and p-block elements in the second period of the modern periodic table.

1. Second Period of the Periodic Table:
The second period consists of 8 elements:
- The first two elements (Li and Be) are in the s-block.
- The last six elements (B, C, N, O, F, and Ne) are in the p-block.

2. Identifying s-block and p-block Elements:
- The s-block elements in the second period are: Lithium (Li) and Beryllium (Be). Hence, there are 2 s-block elements.
- The p-block elements in the second period are: Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), and Neon (Ne). Hence, there are 6 p-block elements.

Final Answer:
Option (C) 2, 6 is correct.
