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

∙ 12y ago
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.
The approximate mass of a proton is 1 atomic mass unit (amu), while the approximate mass of a neutron is slightly heavier at 1.008 amu.

What is the approximate atomic mass of a neutron?
The approximate atomic mass of a neutron is 1 unified atomic mass unit, which is equivalent to 1.008665 atomic mass units when considering the mass excess.
Do the designations hydrogen and neutron for the proton and neutron imply that these two praticles are of equal mass?
No, the designations of hydrogen for the proton and neutron for the neutron do not imply that these two particles are of equal mass. A proton is about 1836 times heavier than a neutron. The terms "hydrogen" and "neutron" were historically used to describe these particles based on their properties and roles in atomic structure, rather than their masses.
What is the difference of mass of a proton and a neutron?
The mass of a proton is slightly lighter than the mass of a neutron. A proton has a mass of approximately 1.67 x 10^-27 kg, while a neutron has a mass of approximately 1.68 x 10^-27 kg.
How many atomic mass units does an electron have?
An electron has a mass of about 0.00054858 atomic mass units (amu) or approximately 1/1836 of a proton or neutron.
What atomic mass is more either proton or neutron?
Neutrons have a slightly higher atomic mass compared to protons. Neutrons weigh approximately 1.0087 atomic mass units, while protons weigh approximately 1.0073 atomic mass units.

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

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 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!
How does the mass of the neutron and the protons differ?
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)
How many atomic mass units does an electron have?
An electron has a mass of about 0.00054858 atomic mass units (amu) or approximately 1/1836 of a proton or neutron.
What atomic mass is more either proton or neutron?
Neutrons have a slightly higher atomic mass compared to protons. Neutrons weigh approximately 1.0087 atomic mass units, while protons weigh approximately 1.0073 atomic mass units.
Each proton and neutron has an atomic mass unit amu?
Yes, that is correct. A proton and neutron each have a mass of approximately 1 atomic mass unit (amu). This unit is commonly used to express the mass of subatomic particles in relation to the standard carbon-12 atom.
What unit of measure do you use to measure the mass of a proton?
Their mass is measured in atomic units 1 atomic unit is 1.660538782×10−27 kg A Proton has a mass of 1.007276466 u (u is the symbol for Atomic Mass) A Neutron has a mass of 1.008664915 u
