The mass of an electron is difficult to find because of the Heisenberg Uncertainty Principle. Either a particle's position or direction can be known, and the more precisely one is measured, the other is subject to more possible variation.
To find the relative uncertainty in the mass of the electron, you would typically determine the absolute uncertainty in the measurement of the electron's mass and then divide it by the measured value of the electron's mass. Finally, multiplying by 100 will give you the relative uncertainty as a percentage.
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.
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
among these Electron has the least mass....
Electron has a mass of about 9.10938215 × 10−31 kg.
The proton mass is about 2,000 times greater than the electron mass.
The proton mass is about 2,000 times greater than the electron mass.
The proton mass is about 2,000 times greater than the electron mass.
The proton mass is about 2,000 times greater than the electron mass.
No, the mass of an electron is roughly 1/1836 the mass of a proton.
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.
The tiny subatomic particle related to the electron that has no electric charge and little mass is the neutrino. Neutrinos are extremely difficult to detect due to their neutral charge and low interaction with matter.
