Question

question 5 (1 point) which subatomic particle has the smallest mass? a electron b neutron c proton

Explanation:

To determine which subatomic particle has the smallest mass, we compare the masses of electrons, neutrons, and protons. Electrons have a much smaller mass (about \(9.109\times10^{-31}\) kg) compared to protons (about \(1.6726\times10^{-27}\) kg) and neutrons (about \(1.6749\times10^{-27}\) kg). Neutrons and protons have almost equal masses, both much larger than that of an electron.

Answer:

a. electron
