Chapter 6, Problem 5STP

Interpretation Introduction

Interpretation:

The block to which element Z belongs needs to be determined.

Concept introduction:

The elements in the groups 13 to 18 are collectively known as p-block elements. The elements present in group 18 are known as inert gas because of their less chemical reactivity. Some of the inert gases are helium, neon, argon etc.

Answer to Problem 5STP

Correct option is B, p-block

Explanation of Solution

Given that the element Z is an inert gas, that means, it belongs to 18 of the periodic table. Group 13 to 18 are collectively known as p-block elements. So, Z belongs to p-block elements. Hence, B is the correct option.

Conclusion

Inert gas belongs to p-block. So, options A, C and D are incorrect.
