Chapter 6, Problem 49A
Interpretation Introduction

Interpretation:

Whether within a group, the element with larger atomic number that other will have larger or smaller atomic radius that the other needs to be determined using examples.

Concept introduction:

The atomic radius of a particular element is the measure of the atoms size. It can also be defined as the distance between the nucleus of the element to its boundary.

Expert Solution & Answer

Answer to Problem 49A

The element with larger atomic number in a group will have larger atomic radius.

Explanation of Solution

As an example, considering group 17 elements fluorine and bromine. Fluorine has atomic number 9 and bromine has atomic number 36. On moving down a group from top to bottom, the atomic size increases.

The number of protons and electrons increases as the atomic number increases down a group. Also, an extra shell is added around the nucleus which results in increase in the overall size of the atom.

Therefore, Br has a larger atomic radius than F.

Conclusion

As on moving in a group from top to bottom, an extra shell around the nucleus is added and atomic number increases thus, the element with the larger atomic number will have larger atomic radius.
