Indicate which subatomic particle (proton, neutron, or electron) correctly matches each of the following phrases. More than one particle can be used as an answer.
- a. possesses a negative charge
- b. Has no charge
- c. has a mass slightly less than that of a neutron
- d. Has a charge equal to, but opposite in sign from, that of an electron
(a)
Interpretation:
The subatomic particle that possesses a negative charge has to be given.
Concept Introduction:
Atoms are made up of even smaller particles. These particles are very small and these are all the building blocks of atoms and they are known as subatomic particles. Protons, electrons, and neutrons are the subatomic particles that are found in atom. Electrons possess a negative electrical charge. Protons possess a positive electrical charge. Neutrons possess no charge and they are neutral.
If the mass is considered to one unit based on one electron, then the relative mass of a proton is equal to 1837 electrons and neutron is equal to 1839 electrons. Neutron is slightly higher in mass than that of a proton.
Explanation of Solution
An atom is made up of subatomic particles namely, electron, proton, and neutron. The subatomic particle that possesses a negative charge is electron only. This is present outside the nucleus of an atom.
(b)
Interpretation:
The subatomic particle that possesses no charge has to be given.

Explanation of Solution
An atom is made up of subatomic particles namely, electron, proton, and neutron. The mass of an atom is mainly contributed by the proton and neutrons that are present in the nucleus. Neutrons do not possess any charge and it has mass slightly higher than that of proton.
(d)
Interpretation:
The subatomic particle that has equal opposite charge from that of an electron has to be given.
