Question

which statement(s) correctly compare the masses of protons, neutrons, and electrons? select two options. protons and neutrons have similar mass. protons and electrons have similar mass. neutrons and electrons have similar mass. protons are smaller than a neutron or an electron. neutrons are smaller than a proton or an electron. electrons are smaller than a proton or a neutron.

Explanation:

Protons and neutrons are found in the nucleus and have approximately the same mass. Electrons are much lighter than protons and neutrons. Protons have a mass of about 1 atomic mass unit (amu), neutrons also about 1 amu, while electrons have a mass of about 1/1836 amu.

Answer:

Protons and neutrons have similar mass.
Electrons are smaller than a proton or a neutron.
