An electron does have mass, but it's so small that it's often considered 0. If the mass of a proton or neutron is 1, then the mass of an electron is about 1/1836.
its because i really dont know
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.
Of the neutron, proton, and electron, the electron has the smallest mass.
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.
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 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 mass of an electron is 9.12 x 10-31 kg
