No, the proton and neutron don't have the same mass. A neutron is about 1.00138 times as heavy as a proton. The neutron is just a bit bigger, as you can see, and when a free neutron decays, it releases a proton and an electron. It might be said that a proton plus an electron equals a neutron, but you might not be able to get a physicist to say that. Links can be found below for more information.
Protons and neutrons do have very nearly the same mass, with the neutron ever so slightly greater. The mass of the proton is about 1.672622 x 10-27 kg, while the mass of the neutron is about 1.672927 x 10-27 kg.
This difference in mass (an energy differential of about 1.293332 MeV/c2) is part of why it is easier for a neutron to change into a proton during beta- decay, than it is for a proton to change into a neutron during beta+ decay.
No they are not. But proton and electron is.
No, neutrons are slightlyheavier. (A protons have about 0.9986 times the mass of a neutron.)
The mass of a neutron is very close to that of a proton, but slightly higher.
Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
Neutrons have the same mass as a proton and be electrically neutral. Protons and neutrons have almost the same mass.
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

The number of protons and neutrons is what determines the mass of an isotope. Even though isotopes of a particular element have the same number of protons, but a different number of neutrons, which causes their mass to be different.
protons and neutrons
Protons and neutrons have near identical mass. One will not have to account for the difference in mass in most calculations.
They are the neutrons. They are in middlem, in nucleus

no
The mass of an atom is concentrated in the nucleus. Protons are a part of the nucleus, but not the entire thing. Neutrons are also in the nucleus and have nearly the same mass as protons.
Neutrons have the same mass as that of a proton. Neutrons and protons are present in the nucleus
No. The mass of neutrons and protons are about the same. The mass of an electron is about 1/1800th the mass of a proton.

Protons and neutrons have about the same mass, but electrons are much, much lighter.
