What is the atomic mass of an electron?
an electron is about 1/1836 amu.
What is the ratio of the mass proton to the mass of an ELECTRON?
Dunno, but the ratio of the mass of a proton to the mass of what prople think of as being an electron is approx 1980. I'd check that if I were you though. Probably OK to +- 5%.
What is Electron Relative mass?
it is usually the mass without the x10^-31
What is the mass of an electron approximately equal to?
1/1836 the mass of a proton
How does the mass of a nucleus compare to a electron?
The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron. In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron. In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron. So take your pick: 1,837 to 516,200.
What can be inferred about the mass of ang electron?
The mass of an electron is approximately 9.11 x 10^-31 kilograms, which is significantly lighter than the mass of a proton or neutron. This implies that electrons contribute minimally to the overall mass of an atom.
What part of an atom is not used in calculating the mass number?
All parts of the atom weigh something but when doing calculations electrons are said to have a mass of 0. This is because they actually have a mass of 1/1836 amu which is insignificantly small and so it is disregarded.
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.
Which subatomic particle has the smallest mass alpha particle neutron electron proton?
among these Electron has the least mass....
What is an electron in an atom?
Electron is a negatively (-) charged particle found in a atom. Unlike proton and neutron, electron is found in orbital shells of atom, but not in nucleus. Electron are very small that is why they don't contribute to the atomic mass of a element. Electron are responsible for forming ions and take part in chemical reaction.
What did Millikan contribute to atomic theory?
He discovered that the weight of an electron is 1836 times smaller than that of a hydrogen atom (atomis mass of 1)
What is the mass of of an electron?
Electron has a mass of about 9.10938215 × 10−31 kg.
