information page (click the link to access the information page. the information page will open in a different tab. to go back to the exam, click on the previous tab). question 10 (5 points) which statement about subatomic particles is true? a) unlike protons or neutrons, electrons have no mass. b) protons, neutrons, and electrons all have about the same mass. c) an electron has far less mass than either a proton or a neutron. d) neutrons have no charge and no mass. e) protons are positive and are the heaviest subatomic particles.

Explanation:

To determine the correct statement about subatomic particles:

• Option a: Electrons do have mass (very small), so a is false.
• Option b: Protons (≈1 amu), neutrons (≈1 amu), and electrons (≈0.0005 amu) have different masses, so b is false.
• Option c: Electrons have a mass of about 1/1836 of a proton/neutron, so they have far less mass. This is true.
• Option d: Neutrons have mass (≈1 amu), so d is false.
• Option e: Protons and neutrons have similar mass (both ≈1 amu), so protons aren’t the heaviest alone, e is false.

Answer:

c) An electron has far less mass than either a proton or a neutron.
