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.

∙ 14y agoYes, electrons have much less mass than neutrons and protons.
Wiki User
∙ 11y agoYes. A neutron is approximately 1839 times more massive than an electron.
Wiki User
∙ 14y agoYes since protons and neutrons contribute most of the atomic mass of the atom.

∙ 12y agoIn their mass, that is about correct.
The volume can not be accurately determined.

If someone picks up an excess of electrons while walking across a carpet their charge would be?
negative protons are positively charged neutrons are neutral electrons are negative the masses of neutrons and protons are approximately equal and electrons, which "orbit" around the nucleus (the protons and neutrons) are much smaller mass-wise protons and electrons charges are equal and opposite
Are there any particles smaller than protons neutrons and electrons?
Electrons are fundamental particles and we can not actually measure the size of an electron (we know we will NEVER be able to). However the size of protons and neutrons can be measured and we know that these particles are made up of other, more fundamental particles which are probably smaller.
How much protons neutrons and electrons are in roentgenium?
Roentgenium has 111 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope -111
What is the same between neutrons and electrons?
When the number of electrons and neutrons are the same, it means that the number of protons will also be the same amount. For example a nitrogen atom has 7 electrons and 7 neutrons, this means that the number of protons will also be 7.
Where is most of the mass located in an atom?
By far it is in the nucleus. Neutrons are very slightly more massive than protons, but not all atoms have neutrons. All atoms will have at least one proton. Protons and neutrons are both much, much more massive than electrons. Relatively speaking.
Which two particles have roughly the same mass?
Protons and neutrons have almost the same mass.
Are electrons larger than neutrons and protons?
no. protons and neutrons are MUCH larger than electrons.
Why are protons neutrons electrons called subatomic particles?
Because they are much smaller than an atom

Are neutrons important in chemical reaction?
No, absolutely not. There are much smaller particles, first Electrons (which are part of reactions), Then Quarks that neutrons and protons are made of (and are part of reactions), and much, much smaller particles after that also are involved in chemical reactions.
Do protons nuetrons and electrons all have about the same mass?
Protons and neutrons have about the same mass, but electrons are much, much lighter.
Where can you find a Nucleus?
In the very centre of a atom. The nucleus is composed mainly of protons and neutrons surrounded by a swarm of much smaller electrons.
What are neutron stare?
Do you mean neutron stars? Any atom you can think of has the same number of electrons as protons in the nucleus. Some stars have collapsed under their own gravity so that the electrons have been squeezed into the nucleus. When they do that, they combine with the equal number of protons to form neutrons in every case. So instead of atoms with neutrons, protons and electrons, you are left with just neutrons, and neutrons are much much smaller than atoms. The densities and gravitational fields in the vicinity are enormous.
How do electrons of an atom compare to planet and the sun?
Inside atoms, there are protons, neutrons, and electrons. Protons are positively charged, neutrons are neutrally charged, and electrons are negatively charged. In most atoms, the number of protons and neutrons are equal, meaning the atom is neutrally charged. However, protons and neutrons are about the same size, while electrons are MUCH smaller. For reasons we don't fully understand, the protons and neutrons stick together in a clump at the center of an atom while the electrons circle around. We call that clump the nucleus. Now, this is very similar to a solar system. The sun is very large, with many smaller planets circling around. The difference is, planets circle around the sun because of gravity, and electrons circle around the nucleus because God likes to screw with us.
What two particles are in the nucleus?
(The constituent particles of an atom are the electron, the proton and the neutron; all three are fermions. However, the hydrogen-1 atom has no neutrons and the hydron ion has no electrons.) WIkipedia
How does protons nuetrons and electrons differ?
All have spin one-half. Protons have a charge of positive one; electrons, negative one; neutrons, neutral. Protons and neutrons have about the same mass; electrons are much less massive. Protons and neutrons have an internal structure -- ie, they are composed of quarks -- while electrons are just themselves. The first two are "hadrons" and the latter is a "lepton."
