Proton and Neutron
OK, in very very round figures, but the neutron actually is more massive.
- In the first approximation, the neutron's mass about as much as a proton plus one electron or (P)938.235 MeV + (e)0.51098 MeV = 938.74598 MeV.
- In the second approximation, the energy of the neutrino, photon, and electron velocities ejected in free neutron beta decay would be added, but I can't find that in my references right now so I'll skip the math.
- There are probably also third approximation terms to account for, if not more.
- As measured, the neutron's mass is 939.529 MeV.
What else can I help you with?
Which two particles in the atom have the same mass?
No two subatomic particles have the exact same mass. The proton and the neutron, however, come close. Neutrons are heavier than protons by only 2.3 X 10-30 kg.
What two particles of the atom are added together to get the atomic mass?
4
What are the two parts of the atom that have a mass of 1 atomic mass unit?
The two parts of the atom that have a mass of approximately 1 atomic mass unit (amu) are protons and neutrons. Protons are positively charged particles found in the nucleus of an atom, while neutrons are neutral particles that also reside in the nucleus. Together, these particles make up the majority of an atom's mass. Electrons, on the other hand, have a negligible mass compared to protons and neutrons.
What particle or particles carry virtually all the mass (weight) of any atom?
Virtually all of the mass of an atom is carried by the proton and the neutron. The electron has very, very little mass relative to these two particles.
What two subatomic have about the same mass?
These particles are: proton and neutron.

Which two subatomic particles have about the same mass?
Ah, isn't it fascinating how the proton and neutron have about the same mass? They're like two peas in a pod, working together to make up the nucleus of an atom. Just imagine them dancing around, creating harmony in the world of particles.
What are the two subatomic particles with a mass?
In the atom, protons and neutrons; the mass of the electron is very small.
What are the two parts of the atom that have a mass of 1 atomic mass unit?

What are the same number of these two particles in an atom?
Protons and electrons.
What two subatomic particles do you add together to get the mass number?
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
What two subatomic particles are added together to determine the mass number?
The two subatomic particles added together to determine the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but both contribute to the mass of an atom.
