Neutrons
The proton has a +1 charge, while a neutron has no charge, and is neutral.
Heavy unstable nuclei can undergo a process known as proton or neutron emission, where they emit a single proton or neutron to reach a more stable state. This emission is a form of radioactive decay, helping the nucleus decrease its mass and improve its stability. Proton emission is more common in very heavy nuclei, while neutron emission occurs in some isotopes that have an excess of neutrons. Overall, these emissions are crucial for understanding nuclear stability and the behavior of heavy elements.
Normal Water (H20) has hydrogen atoms with one proton and Heavy Water (D20) has a neutron and a proton in it H2 atoms.
A proton
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)).
Neutron-proton scattering refers to the interaction between a neutron and a proton. It involves the exchange of a virtual meson between the two particles, which allows them to interact through the strong nuclear force. Studying neutron-proton scattering can provide valuable information about the structure and interactions of the atomic nucleus.
Not all metals are heavy. The heavy ones have more density due to proton and neutron count. Titanium vs gold for instance.
Normal hydrogen has one proton and no neutrons in its nucleus, so it has a mass of one. Heavy hydrogen often called deuterium has one proton and one neutron, so it has a mass of two instead of one. There is also tritium which has one proton and two neutrons, so a mass of three.

One Proton and one Neutron. It's also called Heavy Hydrogen and has one Electron
You are an atom of heavy hydrogen, or deuterium. Most hydrogen has one proton and one electron, which form a neutral atom. But once in a while, a neutron will stick to the proton, and then the atom, which is still hydrogen (it has just the one proton) will be about twice as massive as "regular" or "common" hydrogen. It is another isotope of hydrogen called heavy hydrogen or deuterium.
