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.
Which two particle in an atom have about the 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.
What subatomic particles compose the mass of an atom?
All subatomic particles have mass, bar the photon and the gluon. The masses of some of the most well-known are as follows: Electron: 0.511 MeV/c^2 Proton: 938.272 MeV/c^2 Neutron: 939.565 MeV/c^2 Electron Neutrino: ~2.2 MeV/c^2 N.B: All masses have been expressed using Einstein's mass-energy equivalence (E=m.c^2); the mass is thus expressed in terms of energy/c^2 as the masses (in kg) would be extremely small.
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.
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.
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.
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.

Are electrons much smaller than protons and neutrons?
Within a Neutron there are two Down quarks and one Up quark. Within a Proton there are two Up quarks and one Down quark. You can not break a Electron down any further as it is a Subatomic Particle itself. Now a Up quark's mass is 2.4 MeV/c2, whilst a Down quark's mass is 4.8 MeV/c2. By using this information we can see that a Neutron has a greater mass than a Proton. Electrons have very little mass (0.511 MeV/c2). So to conclude a Neutron has a greater mass of a Proton, and a Proton has a greater mass of an Electron. This should answer the Question.
How much more massive is a proton compared to a electron?
By sheer size, I would assume MUCH larger. But through weight, the proton is much heavier compared to an electron. On any element, the atomic number is the weight of the nuetrons and protons. The weight of electrons is so small and insignificant, it is usual not looked on at the highschool level. And has no effect on the molar mass.
