Some physicists consider that photons, gluons, neutrinos are massless but this affirmation is probable not correct.
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.
The neutron; nmass = 1, 008 664 915 6(6) amu.
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
beta particle
Neutron: Mass: 1,00866491600(43) amu. Charge: neutral James Chadwick, 1932 Electron: Mass: 5,4857990946(22)×10−4 amu. Charge: negative J. J. Thomson, 1897 Proton: Mass: 1,007276466812(90) amu. Charge: positive
Both one proton and one neutron each has a relative mass of 1 a.m.u.
Protons and neutrons have the mass of 1 amu.
The largest subatomic particle (by mass) is the proton. The mass of subatomic particles is measured in atomic mass units (amu). The proton has a mass of 1.007 amu, the neutron has a mass of 1 amu, and the electron has a mass of .0005 amu.
No, an alpha particle has a mass of 4 amu and a charge of +2. It is a helium nucleus. The neutron has a mass of 1 amu and no charge.
The neutron; nmass = 1, 008 664 915 6(6) amu.
This particle is the neutron: 1,00866491600(43) amu.
No, that would be a neutron. A proton is a nuclear particle with a mass of 1 AMU and a 1+ charge
Neutron: Mass: 1,00866491600(43) amu. Charge: neutral Electron: Mass: 5,4857990946(22)×10−4 amu. Charge: negative Proton: Mass: 1,007276466812(90) amu. Charge: positive
protons --- rel. mass 1 amu, rel. charge +1, location in the nucleus. neutrons --- rel. mass 1 amu, rel. charge 0, location in the nucleus. electrons --- rel. mass 0 amu, rel. charge -1, location outside the nucleus.
The mass and the charge. Protons are positively charged. Electrons are negatively charged. Neutrons have no charge. Protons and neutrons have similar mass (about 1 amu). The mass of electron is about 1822 times less than that of protons / neutrons.
This atomic particle is the neutron.
This particle is the electron with a mass of 5,485 799 094 6(22)×10−4 amu.
