Verified step by step guidance1
Recall that an atom consists of three main subatomic particles: protons, neutrons, and electrons.
Understand the properties of each particle: protons have a positive charge (+1), electrons have a negative charge (-1), and neutrons have no electric charge (0).
Recognize that neutrons are located in the nucleus of the atom along with protons.
Know that the mass of a neutron is approximately 1 atomic mass unit (amu), which is similar to the mass of a proton.
Use this information to identify the correct statement: a neutron has no electric charge and a mass of about 1 amu.
