I assume that you mean a "neutron" with a "t". If so, the mass is very similar to that of a proton (a neutron is roughly 1.0013 times as heavy (http://education.jlab.org/qa/particlemass_02.html)).
no
No; the mass of proton is similar to the mass of neutrons.
Yes, a proton has mass. The mass of a proton is approximately 1.67 x 10-27 kilograms.
Yes. An atom of He will be twice that of H because it has twice as many neucleic particles (a proton and neutron vs a proton) There really isn't an average mass of an atom. You can look up the masses of atoms though, on the Periodic table of Elements
Yes, a proton has mass.
The mass of a proton is equal to a neutron.
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
A proton. A proton has a mass of 1 a.m.u. while an electron has a mass of 1/1840 a.m.u.
the neutral or no charge particle of an atom:it is located in the nucleus;has the same mass as the proton.
The proton mass is approximately 0.938 GeV.
A proton has a mass of 1 AMU (one atomic mass unit)
No, the mass of an electron is roughly 1/1836 the mass of a proton.
