Chapter 6, Problem 8STP

Interpretation Introduction

Interpretation:

The groups or block in which the metalloids are found needs to be determined.

Concept introduction:

The modern periodic table consists of vertical rows, which are called as groups and horizontal rows, which are called as periods. There are 7 periods and 18 groups in the periodic table.

Answer to Problem 8STP

Metalloids are found in groups 13 through 17. Correct option is B.

Explanation of Solution

Reason for correct option:

Metalloids are the elements which consist of properties of both metals and non-metals. Some examples of metalloids are Boron, silicon, arsenic etc. These elements are present in the p-block of the periodic table, that is, groups 13 to 17. So, B is the correct answer.

Conclusion

Reason for incorrect options: The d-block consists of inner transition metals, such as, Iron, zinc etc. So, A is incorrect option.

The f-block consists of lanthanides and actinides. So, C is incorrect option.

s-block consists of two groups, that is, 1 and 2. Group 1 consists of alkali metals and group 2 consists of alkaline earth metals. So, D is incorrect option.
