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.
Distinguish between the subatomic particles in terms of relative charge and mass?
Proton: Charge= +1.60 x 10-19 C; Relative Charge=+1; Mass: 1.672 x 10-24 g; Relative mass= 1 amu Electron: Charge= -1.60 x 10-19 C; Relative Charge=-1; Mass: 9.05 x 10-28 g; Relative mass= amu ~(1/1840 amu) Neutron: Charge= neutral ; Relative Charge=0; Mass: 1.674 x 10-24 g; Relative mass= 1 amu
How do the masses of the protons and the neutrons compare to the mass of the electrons?
If we give them relative numbers, the proton has a mass of 1.0073, the neutron has 1.0087 and the electron has 5.486 X 10 to negative 4.
The 3 subatomic particles?
The three subatomic particles in an atom are protons, neutrons, and electrons:Protons have a relative mass of 1 and a charge of +1, and they are found in the nucleus of an atom.Neutrons have a relative mass of 1 and no charge, and they are also found in the nucleus of an atom.Electrons have a relative mass of 1/1836 and a charge of -1. They are found in specific orbits around the nucleus and are held in these orbits by the positive charge of the protons in the nucleus.
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.
Mass of electron compared to proton?
Mass of electron is about 1837 times less than the mass of proton
What is Electron Relative mass?
it is usually the mass without the x10^-31
What is the number of atomic mass in an atom?
Relative mass number of an electron is 0
What are the charges and relative masses of the main subatomic particles?
electron = relative charge = 1- relative mass = 1/1840 proton = relative charge = 1+ relative mass = 1 neutron = relative charge = 0 relative mass = 1
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
What is the Ar of Carbon?
The Relative Mass (Ar) of carbon is 12. The Relative mass can be found very easily, it is the top number of the electron in the periodic table.
If a proton had a mass of 1 what is the mass of an electron and neutron relative to the mass of the proton?
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron
How do you find the relative uncertainty in the mass of the electron?
The mass of the electron is 9,109 383 56(11)×10e-31 kg.The uncertainty is +/-11 for the last two decimals.
What have almost equal masses to the proton?
No, it isn't. The mass of an electron is significantly smaller than that of a proton.The mass of 1,800 electrons is about the same as the mass of one single proton.The antiparticle of the electron, the positron, has the same mass as the electron.the mass of the electron is not the same to the mass of the proton
What are Atoms 3 particles?
Proton - Relative Atomic Mass of 1, charge of 1. Neutron - Relative atomic mass of 1, charge of 0. Electron - Negligible mass (0), charge of -1.
What are the relative atomic mass of subatomic particles in atom?
neutrons are heavier than protons by a bit more than the mass of electron.
