∙ 15y agoThe mass of a proton is 2000 times the mass of an electron.
Mass of electron: 9.10938 * 10-31 kg
Mass of proton: 1.67262 * 10-27 kg
Mass of neutron: 1.67493 * 10-27 kg
Note that protons and neutrons weigh approximately the same (neutrons are slightly heavier), but electrons are MUCH lighter than both of them.
The MASS of the electron is much smaller than neutrons and protons. It is common, but incorrect, to use mass and weight interchangeably. They are not synonymous.

∙ 13y agoThe mass of a proton is approximately 1836 times greater than the mass of an electron. A proton has a mass of about 1.67 x 10^-27 kilograms, while an electron has a mass of about 9.11 x 10^-31 kilograms.

∙ 15y agoFor all intents and purposes, the electron is virtually massless, particularly when compared to protons and neutrons, which are the primary constituent particles responsible for the mass of an atom. The contribution of electrons to the mass of an atom is negligible. 2000 times as heavy as an electron

A proton is: 1.672 621 637 x 10-27 kg
and an electron: 9.109 382 15 x 10-31 kg
So a proton is more than 1800 times heavier.

∙ 15y agomass of a proton is 1 A.M.U
A.M.U stands for Atomic Mass Unit
mass of electron is around 1/1387 A.M.U
so it is fairly negligible

∙ 15y agoa proton has a mass of 1. an electron has a mass of 1/1860 or approximately 1/2000 Thus, a proton weights approximately 2000 times more than an electron.

∙ 15y agoThe mass of a proton is 1.6726 x 10-24 grams. The mass of an electron is 1/1836 that of the proton (ie the mass of 1836 electrons = mass of 1 proton)

∙ 8y agoElectron has a very low mass than a proton. Protons have a positive charge.
The mass of an electron is much smaller than the mass of a proton. An electron has a charge of -1, while a proton has a charge of +1.
yes the mass of an electron is much tinnier fraction of the mass of an atom
Well if I'm not mistaking, which I might be. It has 55 protons and I'm not positive on electrons but I would guess 55 also
If you compare the mass of a positron to an electron, or of a proton to an anti-proton, and so forth, the mass is the same, even though the charge is reversed. Negative charge does not mean negative mass, it has no bearing on the mass.
The mass of an electron is atomic mass units is 5,485 799 090 70(16); the mass of the electron is not an atomic mass.
An electron.
the electron is the smallest in terms of mass. 9.11E-31kg/electron 1.67E-27kg/neutron 1.67E-27kg/proton
A proton has a mass over 1,800 times that of an electron (taken from this already-asked question: http://wiki.answers.com/Q/Is_a_proton_or_electron_heavier)
The proton mass is about 2,000 times greater than the electron mass.
The proton mass is about 2,000 times greater than the electron mass.
A electron cloud, a electron, protron,neutron,and the nucleus
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
black
Mass ratio proton (neutron)/electron: 1 836
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.
Well, that's kinda a trick question because an electron is pure energy. An electron particle is also the smallest of the 4, so its the electron (eventhough an electron is a weichtless particle such as a graviton or magneton! Hope I helped!!
