About 1/1800.
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
1.66 X 10 -27 kg (mass of proton/neutron)/9.109 X 10 -31 kg ( mass of electron) = 1822 times greater ===============
The two important characteristics of a neutron are its mass and charge. These are described below. 1) Mass of neutron. The mass of a neutron is equal to mass of a proton. The relative mass of neutron in 1 u. the absolute mass of a neutron is 1.6 * 10^-24 gram. 2) Charge of neutron. Neutron has no charge. It is electrically neutral. The two important characteristics of a Proton are its mass and charge. These are described below. 1) Mass of proton. The Proton is actually a hydrogen atom which has lost its electron. Since mass of an electron is very small, we can say that mass of proton is equal to mass of a hydrogen atom. The relative mass of neutron in 1 u. the absolute mass of a neutron is 1.6 * 10^-24 gram. 2) Charge of proton. The charge of a proton is equal and opposite to the charge of an electron. So absolute charge of a proton is 1.6*10^-19 coulomb.
The exact contribution varies from atom to atom, since different atoms have different numbers of neutrons. However, in a simple system of one proton, one electron, and one neutron (called a deuterium atom), the neutron contributes roughly as much as the proton does, since its mass is almost (but not quite; the neutron is heavier) equal to that of the proton. To be precise, as listed at http://www.newton.dep.anl.gov/askasci/gen01/gen01078.htm, Mass of proton : 1,6726 x 10^(-27) kg Mass of neutron: 1,6749 x 10^(-27) kg Mass of electron: 0,00091x10^(-27) kg
um if i remember correctly an electron has 1840 times less mass than a proton and an electron + a proton makes a neutron so a neutron is one 1840th more hevyer than a proton :P esther says: that is rude so the correct answer is no
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
1.66 X 10 -27 kg (mass of proton/neutron)/9.109 X 10 -31 kg ( mass of electron) = 1822 times greater ===============
The proton mass is about 2,000 times greater than the electron mass.
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
The neutron has a mass that is nearly equal to the combined mass of a proton and an electron. This is due to the fact that the neutron is slightly heavier than the proton, while the electron has a much smaller mass.
an electron is much lighter than a proton or neutron.
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
A neutron is actually heavier than a proton because a neutron is made up of a proton + an electron + subatomic particles. The relative masses are: * Mass of neutron: 1,6749 x 10^(-27) kg * Mass of proton : 1,6726 x 10^(-27) kg * Mass of electron: 0,00091x10^(-27) kg
One neutron is approximately equal in mass to one proton. Since an electron is much smaller in mass compared to a neutron or a proton, it would take a large number of electrons to equal the mass of one 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.
