What is the mass of an electron compared to a proton?
The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1.

How many electron masses is a proton mass?
Answer: About 1837 electrons will equal the mass of a proton.
Which is larger a proton or an electron?
Atomic particles Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron.
Why is proton heavier than electron?
An atom consists of a nucleus which contains neutrons and protons , electrons revolve around the nucleus. Only nucleus contribute to the mass of the atom because protons are heavier in weight than electrons.
How do you find the mass of a proton in MeV c2?
For example, if the rest mass of a proton is converted entirely into energy, then E = mc2 = (938.27 MeV/c2)c2 = 938.27 MeV. It is useful to note that 1 u of mass converted to energy produces 931.5 MeV, or 1 u = 931.5 MeV/c2.
Is MeV bigger than eV?
A MeV is the Mega electron-volt, e.g. million times more than eV. One eV is defined as the energy, that an electron ( or an other single-charged(q=1.6*10^-19 Coulombs) particle) gains when it undergoes a potential difference of 1 Volt.
How many times larger is a proton than an electron?
A proton is about 1835 times more massive than an electron. If you are asking about their physical dimensions – no one knows. Scientists currently do not know how small electrons are. They are smaller than we can currently measure and may not have a size at all!
How much heavier is proton than an electron?
1840 times heavier
Proton is 1840 times heavier than electron.
What is mass of proton and how to calculate it?
– Mass Number is the number of protons and neutrons in an isotope. This is a whole number. – Atomic Mass is the mass of the entire atom of an isotope. This includes electrons as well as a slight change in mass due to binding energy. – Average Atomic Mass is the weighted average of the isotopes for an element.
Why mass of proton is greater then mass of electron?
Yes.The E/M ratio of a electron is always greater than a proton because the electron is 1840 times lighter than the proton. The E/M of a particle increases when the mass decreases and when the mass increases,the E/M ratio decreases. Is a charge to the mass ratio of an electron greater than a proton?
What has same mass as proton?
Thus an antiproton (p) has the same mass as a proton (p), but the opposite charge (-1). Thus an antielectron (e + or e ) has the same mass as an electron but the opposite charge (+1). FYI When matter meets antimatter both annihilate each other to become pure energy!
Which has a greater mass an electron or a proton?
– Mass of proton: 1.67×10−27 kg. – Mass of electron :9.1×10−31 kg; – Now divide the mass of proton to the mass of electron – Quick Answer. A proton is approximately 1850 times heavier than an electron.
