- How does the mass of an alpha particle compare to that of a . . . - Answers
A particle that has a mass of 1 and a charge of 1 plus is a proton The electron is the lightest particle in the list A proton is 1836 times more massive than an electron
- Electrons and holes: how can holes have a mass? - Physics Forums
The effective mass is related to the new dopant valence band gap (associated with holes) and the dopant conduction band gap (associated with electrons) Effective mass is defined by analogy with Newton's second law F = m a Since we can measure the applied force and the resultant acceleration, we can compute "effective" mass
- What has the least mass in an atom? - Answers
The electron is the subatomic particle with the least mass It has a mass of about 1 1836 of a proton or neutron No actually, the neutrons and the protons of an atom are relatively the same in mass
- What is Mass? Electrons vs Photons - Physics Forums
Can someone tell me what mass is other than particles with mass react to a gravitational field? Electrons and photons are quite similar, both are thought at the moment to be elementary particles, both exhibit wave particle duality
- Is the mass of an electron about 2000 times that of a proton . . . - Answers
How many times is proton heavier than electron? The ratio of a proton's rest mass to an electron's rest mass is 1836 15267247:1 For more information, follow the link below
- Learn About Neutrino Masses and Speed - Physics Forums
Experiments clearly showed a continuous spectrum of the electron energy, so a third particle has to take the missing energy (and momentum) away Quantum mechanics allows to predict the electron energy spectrum depending on the (known) electron mass and the unknown neutrino mass
- Understanding Electron Volts: The Main Unit of Energy in Physics
The electron volt (eV) is defined as the energy gained by an electron when accelerated through a potential difference of one volt, equating to approximately 1 6 x 10^-19 joules It serves as a crucial unit in atomic and particle physics, allowing for easier calculations of energy, mass, and momentum in these fields The use of eV simplifies the representation of kinetic energy, especially when
- What is the weight of an electron? - Answers
The mass of an electron is 9 109 382 15(45) × 10-31 kilograms (Kg) On Earth the weight of an electron is the mass times gravity That is about 8 9278 x10-30 As a note, due to Newton's Second
