Chapter 19, Problem 2A

Interpretation Introduction

Interpretation:

The size of the atom’s nucleus and their comparison with the overall size of the atom needs to be explained.

Concept introduction:

The size of the nucleus is s small as compared to the atom’s overall size.

Answer to Problem 2A

The size of the nucleus of an atom is near ${\text{10}}^{\text{-15}}\text{m}$ which is equal to the about $\frac{\text{1}}{\text{100,000}}$ times of the overall size of the atom.

Explanation of Solution

On the bases of Rutherford’s experiment, most of the space of the atom is empty and a tiny portion at the center of the atom is positively charged which is known as the nucleus. According to the version of Rutherford’s observation, the size of the nucleus is ${\text{10}}^{\text{-15}}\text{m}$ approximate while the size of the atom is approx ${\text{10}}^{\text{-10}}\text{m}$ . Hence the size of the nucleus is equal to the $\frac{\text{1}}{\text{100,000}}$ times of the size of the atom.

Conclusion

  ${\text{10}}^{\text{-15}}\text{m}$ Is the size of the nucleus which is so small as compared to the total size of the atom.
