How does the mass of the neutron compare with the mass of the proton?
The mass of a neutron is slightly greater than the mass of a proton. The neutron has no electric charge while the proton has a positive charge (+1 elementary charge). The mass of a neutron and a proton are 1.67492729(28)×10−27 kilograms and 1.672621637(83)×10−27 kilograms respectively. That makes the neutron about 25/10,000ths more massive than the proton.
What is heavier meson or proton?
meson is heavier than electron but lighter than proton
Which two particles in an atom have about same mass?
Proton and NeutronOK, 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.

How would you describe the mass of a proton and neutron?
How the masses of elementary particles are expressed depends on who you are, or at least on what you do. The obvious way to do it is in straightforward SI units, i.e. in Kg. In these units the proton mass is 1.6726 X 10-27 Kg and the neutron mass is 1.6749 X 10-27 Kg. The people most concerned with particle masses are particle physicists. Einstein's famous equation e = mc2 shows the exchange rate between mass and energy. To most people this is fascinating, but hardly a daily concern. To a scientist working with elementary particles, the interchange between mass and energy is a daily occurrence. To avoid continual finicky calculations, many physicists express particle masses in terms of their energy equivalent. The energy unit used is the electron-Volt, or eV. This is the kinetic energy of an electron which has been accelerated by a potential difference of 1 Volt. The eV is rather small, so most masses are given in MeV or million electron-Volt. The mass of a proton is 938.272 MeV and of a neutron is 939.566 MeV.

Which more mass a- proton or electron?
A Proton is made up of Subatomic Particles, these include Quarks and Leptons. Within a Proton are two Up quarks and one Down quark. An Up quark has a mass of 2.4 MeV/c2, whilst a Down quark has a mass of 4.8 MeV/c2. An Electron is a type of Lepton, so we can not break it down any further. An Electron has very little mass 0.511 (MeV/c2). So using the information provided we can safely say that a Protons mass is greater than an Electrons mass. This should answer the Question.
How do the masses of protons and neutrons compare?
The mass of a proton is about 1.672621777 x 10-27 kg. The mass of a neutron is about 1.674927351 x 10-27 kg. The equivalent energy of a proton is 938.272046 MeV/c2. The equivalent energy of a neutron is 939.565378 MeV/c2. The difference is 1.293332 MeV/c2, which is the amount of energy released when a down quark is converted into an up quark, changing the neutron into a proton during beta- decay, releasing an electron (0.510998928 MeV/c2) and an electron antineutrino (< 2.2 eV) plus energy of about 0.782333 MeV/c2.
What is the muon's mass?
Muons decay by various methods, primarily, due to the weak interaction, into an electron and two neutrinos. The mass of the muon is 105.7 MeV/c2, with the mass of the electron being 0.511 MeV/c2, and the mass of the neutrino is less than 2.2 eV/c2. As a result, the loss of mass from muon decay, which is carried away as energy, is around 105.2 MeV/c2.
Calculate the energy required to remove one proton and one neutron from Helium 4?
Calculate the rest energy of the alpha particle and the products using E=mc^2, then take the difference (initial - final) between the initial and final states. If your final proton and neutron are independent, use the individual proton and neutron mass in your calculation. If they come off as a deuterium, use the mass of deuterium in the calculation. So you get E(4He) - E(2H) -E(mp) - E(mn) in the former case, and E(4HE) - 2E(2H) in the latter case.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
Does electron weigh more or less then proton and neutron?
Protons are made up of Subatomic Particles, in this case a Proton Atom is made up of two Up quarks, and one Down quark. The mass of an Up Quark is 2.4 MeV/c2 and the mass of a Down quark is 4.8 MeV/c2. Electrons are still in the Subatomic Particle Table, an Electron is a type of Lepton. An Electron's mass 0.511 MeV/c2 which is a lot less than a Proton, even less than a Up quark itself (the lightest quark). In most cases when talking about Atoms and their mass Electrons don't normally have an effect on their mass, only the Neutrons and Protons in the Atom. This should answer the Question.
What is heavier meson or proton?
meson is heavier than electron but lighter than proton
Is the mass of a proton half the mass of a electron?
No. The mass of a neutron is far, far, far greater than the mass of an electron. In fact, the mass of a neutron is approximately about 1840 times greater than the mass of an electron. The particle that has exactly the same mass as an electron is its antiparticle, the positron.
