Chapter 9, Problem 117A

Interpretation Introduction

Interpretation: The comparison between neutrons and protons with respect to their charge, mass, and position in the atom is to be stated.

Concept Introduction : An atom is a tiny particle of matter. It has three subatomic particles electrons, neutrons, and protons. All are different from each other with respect to their charge, mass, and position in the atom.

Answer to Problem 117A

The comparison between neutrons and protons with respect to their charge, mass, and position in the atom is:

	Neutron	Protons
Charge	It has no charge, or it is neutral.	It has a positive charge or $\text{+1}\text{.6}\times {\text{10}}^{-19}\text{C}$
Mass	It has $\text{1}\text{.67}\times {\text{10}}^{-27}\text{kg}$.	It has $\text{1}\text{.67}\times {\text{10}}^{-27}\text{kg}$.
Position	It is present inside the nucleus.	It is present inside the nucleus.
