What two subatomic particles have the greatest mass?
a
protons and neutrons
b
neutrons and electrons
c
protons and electrons
a) Protons and neutrons.
The correct answer is choice (a) protons and neutrons. Protons and neutrons are both located in the nucleus of an atom and are collectively known as nucleons. Both particles have similar masses, with protons having a mass of approximately 1 atomic mass unit (amu) and neutrons having a mass of approximately 1 amu as well.
To determine the answer to this question without relying on memory, you would need to have some basic knowledge of atomic structure. Specifically, you would need to understand the composition of an atom and the location of protons, neutrons, and electrons within it.
One way to find the answer would be to consult a reliable source such as a textbook, scientific article, or educational website that provides information about atomic structure. These resources would explain that protons and neutrons are located in the nucleus, while electrons are found in electron shells surrounding the nucleus. Additionally, they would also provide information about the relative masses of these subatomic particles.
By considering the information from these sources, you could conclude that protons and neutrons have the greatest mass among the given options.
