What is the approximate mass of a proton and neutron in atomic mass units?

The total mass of protons and neutrons in the nucleus was traditionally called the 'Atomic weight', but in more recent times the term 'Relative Atomic Mass' has been used instead. This is really a better term as the mass is relative, and not an actual weight in terms of a weight unit like grams.
One has to distinguish between the mass of the element as it exists in most common form, which may be a mixture of isotopes, and the mass of one particular isotope where all atoms are identical. thus Uranium as found in nature is neither 235 or 238, but a weighted figure depending on proportions of the isotopes.

∙ 14y agoProtons and neutrons don't have the same mass. A neutron is slightly heavier than a proton, which explains why a proton can be split into a proton and electron i beta-decay. A free proton weighs 1.00727646677 amu and a free neutron 1.0086649156 amu. In a nucleus the proton and neutron weighs less. The mass deficiency is caused by binding interactions between adjacent protons/neutrons.

Do the designations hydrogen and neutron for the proton and neutron imply that these two praticles are of equal mass?
The neutron is a little heaviest than the proton. The mass of a proton is 1,00727646677(10) atomic mass units. The mass of a neutron is 1,008664915 6 (6) atomic mass units.
What is the difference of mass of a proton and a neutron?
Both weigh 1.66053886 x 10-27 Kilograms or 1 Atomic Mass Unit.

What measurement is the mass of a proton?
atomic units. A proton has a mass of 1 atomic unit, and so does a neutron. the mass of an electron is very small, and almost negligible

Each proton and neutron has an atomic mass unit amu?
Each proton and neutron has an atomic mass unit (amu) of: 1 3 4 2
What is a protons mass calculated by?
They are calculated by atomic mass units (amu) proton-1amu neutron-1amu electron-0amu
How do the masses of protons and neutron compare to the mass of electrons?
Proton: 1,007 276 466 77(10) Atomic Mass units (u) Neutron: 1,008 664 915 6 (6) atomic mass units (u) Electron: 5,485 799 094 3(23).10-4 atomic mass units (u) If you set the mass of an electron as 1 Then the mass of a proton is 1835 (Approx) The mass of a neutron is 1836 (Approx)
What unit is used to measure the mass of protons and neutrons?
Atomic mass is measured in atomic mass units (amu).
What are the mass of electron proton and neutron?
one one zero
Which weighs more proton neutron electron?
A Neutron weighs more than a proton. Than an electron. A Neutron weighs the most, and an electron weighs the least. A proton is in the middle. Although there are these three sub atomic particles, an atom is made up of 99 percent empty space! But from greatest to least in mass, it goes neutron, proton, then electron!
