The rest mass energy of an electron positron pair is?
Twice the mass of the electron, since the positron has the same mass of the electron. Or the equivalent, in energy units.An electron has a mass or energy of 511 keV.
Relative mass of electron?
1/1840 the mass if a hydrogen atom.
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.
What was the mass of the electron determined to be?
The mass of an electron is:0.000548579867 atomic mass units (amu)or,9.10938188 × 10-31 kilogramsor,9.10938188 × 10-28 grams
What is the difference between rest mass and effective mass of electron?
mass
Is the mass of an electron about equal to the mass of a protron?
The mass of an electron is 9.1095x10^-28 grams and the mass of a proton is 1.6726x10^-24 grams. So while both are very small relative to our macroscopic world, protons are nearly 2000 times larger than electrons.
What is the mass of 1 electron?
1/1836 of an electron is the mass of an electron. It is so small they aren't even calculated in the Atomic Mass of an element
Compare the mass of an electron to a proton.?
Electrons weigh in at about 9.1 x 10^-28 grams and protons about 1.67 x 10^-24 grams, making the proton about 1,837 times heavier than the electron. This is roughly about the same weight of a rabbit compared to an elephant.
Is the mass of one electron equal the the mass of one atomic mass unit?
Since "amu" stands for "atomic mass unit" ... maybe. "mass unit" is kind of a meaningless phrase; it could refer to grams, kilograms, slugs, or whatever.
Is the mass of a proton half the mass of a electron?
No. The mass of a neutron is far, far, far greater than the mass of an electron. In fact, the mass of a neutron is approximately about 1840 times greater than the mass of an electron. The particle that has exactly the same mass as an electron is its antiparticle, the positron.
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.
Who has the smallest mass electrons protons or neutrons?
Of the neutron, proton, and electron, the electron has the smallest mass.
The rest mass energy of an electron positron pair is?
Twice the mass of the electron, since the positron has the same mass of the electron. Or the equivalent, in energy units.An electron has a mass or energy of 511 keV.
What is the mass of of an electron?
Electron has a mass of about 9.10938215 × 10−31 kg.
How does the mass of an electron compared to the mass of proton?
The proton mass is about 2,000 times greater than the electron mass.
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.
