They are not.
No, a neutron is about 1836 times the mass of an electron
No, a neutron is much more massive.
A neutron has approximately the same mass as a proton. Electrons have much lower mass.
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.
The electron is the smallest having about 1/1836th the mass of a proton or neutron, which means that basically an electron has no mass. The neutron and proton weigh the same both having a mass of 1.
In beta decay, the nucleus of the atom emits an electron. This is a new electron, not one of the electrons in the electron cloud. This does indeed have the effect of changing a neutron into a proton, because total charge has to be conserved - if a new negative thing exists, there has to be a new positive thing too. But the mass has to stay the same too - conveniently, protons and neutrons have almost the same mass.
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
no
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
c) neutron Neutrons are nuclear particles with approximately the same mass as a proton but with no electrical charge. They contribute to the nucleus of an atom along with protons.
The electron is the smallest of these entities, being a subatomic particle with a mass much smaller than that of a neutron or an ion. Neutrons and ions are composed of multiple subatomic particles and have greater mass compared to electrons.
