What has the least mass - electron neutron proton nucleus?
LEAST mass? That would be photos or neutrinos, which have no mass at all. Where Least is greater than zero? Electrons, probably; an electron is 1/1836th of a proton, I seem to recall. Neutrinos actually have a small nonzero mass, so small it has yet to be determined. No neutrino has a mass of more than a few eV, the electron has a mass of about 0.5MeV.
Who discovered the charge to mass ratio for the electrons?
Millikan found the charge of an electron by his famous oil drop experiment. J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass. With these two values one can find the mass of electron by dividing the charge value by its specific charge.
What is the difference between rest mass and effective mass of electron?
The rest mass of an electron is its intrinsic mass at rest, which is approximately 9.11 x 10^-31 kg. The effective mass of an electron is a concept in solid-state physics that describes how an electron behaves in a crystalline solid as if it were a free particle with a different mass due to interactions with the crystal lattice. The effective mass can be different from the rest mass and varies depending on the material and the electron's energy level.
How is an electron's wavelength related to its speed and mass?
The wavelength of an electron is inversely proportional to its speed and directly proportional to its mass. This means that as the speed of an electron increases, its wavelength decreases, and as the mass of an electron increases, its wavelength also increases.
Relative mass of electron?
1/1840 the mass if a hydrogen atom.
Why effective mass of electron is negative at the top of valence band?
The effective mass of an electron in a solid is determined by its curvature of the energy band. At the top of the valence band, where the curvature is negative, the effective mass of the electron is also negative, reflecting the opposite relationship between the momentum and velocity of the electron in this region. This negative effective mass indicates that the electron behaves as if it has a negative charge moving in the opposite direction.

What is a particle of relatively negligible mass?
A photon is a particle with negligible mass, whose energy and momentum are determined by its frequency and wavelength. It is a fundamental particle that carries electromagnetic radiation.
What does the atomic mass of an electron represent?
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.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
What did Robert milikan discover?
Millikan's oil-drop experiment demonstrated that charge is quantized, and that the quantum of charge ... the 'elementary' charge ... is 1.6 x 10-19 Coulomb.
How is mass and volume determined in density?
Mass and volume are not determined by density. Rather density is determined by mass and volume
Which subatomic particle has the smallest mass alpha particle neutron electron proton?

What is the mass of of an electron?

How does the mass of electron compare to the mass of the proton?
The proton mass is about 2,000 times greater than the electron mass.
How does the mass of a proton compared to the mass of the electron?
The proton mass is about 2,000 times greater than the electron mass.
