How is neutron mass calculated?
The mass defect can be calculated using equation Δm = [Z(mp + me) + (A – Z)mn] – matom, where: Δm = mass defect [atomic mass unit (amu)]; mp = mass of a proton (1.007277 amu); mn = mass of a neutron (1.008665 amu); me = mass of an electron (0.000548597 amu); matom = mass of nuclide X Z A (amu); Z = atomic number ( …
What is the mass of a neutron in grams?

How did Chadwick calculate the mass of the neutron?
To prove that the particle was indeed the neutron, Chadwick measured its mass. He could not weigh it directly. Instead he measured everything else in the collision and used that information to calculate the mass. For his mass measurement, Chadwick bombarded boron with alpha particles.
What is the mass of a neutron and electron *?
Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged. Electrons have a mass of approximately 0 amu, orbit the nucleus, and have a charge of -1.
Who calculated mass of neutron?
It is remarkable that the neutron was not discovered until 1932 when James Chadwick used scattering data to calculate the mass of this neutral particle.
What is the relative mass and charge of a neutron?

What is mass of 1 mole of neutron?
Mass of one neutron= 1.675×10^ -27 amu. Mass of one mole neutrons=1.675×10^-27×6.02×10^23=10.0835×10^-4 amu.
