Question

Which best describes the mass of protons, neutrons, and electrons?

A. Neutrons have a much larger mass than protons and electrons.
B. Protons have a much larger charge than neutrons and electrons.
C. Electrons have a much larger mass than protons and neutrons.
D. Neutrons and protons have a much larger mass than electrons.

Answer 1

Neutrons and protons have a much larger mass than electrons.

Step-by-step explanation:

The best description of the mass of protons, neutrons, and electrons is that neutrons and protons have a much larger mass than electrons. The mass of a proton is approximately 1.67 x 10^(-27) kilograms, the mass of a neutron is also approximately 1.67 x 10^(-27) kilograms, while the mass of an electron is approximately 9.11 x 10^(-31) kilograms. Therefore, protons and neutrons contribute most of the mass in an atom, with electrons having a much smaller mass.
