A neutron bomb is actually a small thermonuclear bomb in which a few kilograms of plutonium or uranium, ignited by a conventional explosive, would serve as a fission “trigger” to ignite a fusion explosion in a capsule containing several grams of deuterium-tritium.
This is done using heavy water, or water made from hydrogen with extra neutrons. The free neutrons hit the water atoms and transfer some of their kinetic energy to the water, heating it up. The slow neutron is able to hit the U-238 atom, which makes it unstable and break apart.
Atomic number (
proton number) plus neutron number equals
mass number: Z + N = A. The difference between the neutron number and the
atomic number is known as the neutron excess: D = N - Z = A - 2Z.

A neutron is not made of a proton, electron and an antineutrino. These particles are only its decay products. A neutron is made of 3 quarks, one up quark, and 2 down quarks and many many "intermediate particles" called gluons which carry the interaction between the quarks.
There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel each other and unlike charges attract each other. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.
Examples of Negative IonsFluoride is sometimes added to community water supplies. Your dentist may also give you a flouride treatment. The negative charge (fewer protons than electrons) for an anion is shown by a number and minus sign after the formula. If there's just a minus sign, it means the charge is minus 1.
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.
Electrons are in constant motion as they circle around the nucleus of that atom. Electrons are said to have a negative charge, which means that they seem to be surrounded by a kind of invisible force field. This is called an electrostatic field. Protons are much larger and heavier than electrons.
neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.
Structure Of The Atom: Our current model of the atom can be broken down into three constituents parts – protons, neutron, and electrons. Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge.
Proton and electron stars cannot exist at all, because they have the same magnetic charge and repel each other. The magnetic force is about 1,000,000,000,000,000,000,000,000,000,000,000,000 times stronger than gravity so the stars, if somehow created, would instantly fly apart due to magnetic repulsion.

Properties. Neutron matter is equivalent to a chemical element with atomic number 0, which is to say that it is equivalent to a species of atoms having no protons in their atomic nuclei.
Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).
The mass of a neutron is slightly greater than the mass of a proton, which is 1 atomic mass unit (amu). (An atomic mass unit equals about 1.67×10−27 kilograms.) A neutron also has about the same diameter as a proton, or 1.7×10−15 meters.
A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral. Any particle, whether an atom, molecule or ion, that contains less electrons than protons is said to be positively charged.
To the best of our understanding, the proton is a truly stable particle, and has never been observed to decay. Because of the various conservation laws of particle physics, a proton can only decay into lighter particles than itself. It cannot decay into a neutron or any other combination of three quarks.
Electrons have mass, charge, angular momentum, an intrinsic magnetic moment and helicity, but they have no known substructure. No two electrons can occupy the same space at the same time. They are part of every atom but they can exist separately on their own as well.
The nucleus makes up a tiny proportion of the space occupied by an atom, while the electrons make up the rest. According to quantum electrodynamics, the space is filled by an electron field around the nucleus which neutralizes its charge and fills the space defining the atom size.
As others said, the "proton decay" process you wrote down is forbidden, precisely because the neutron is heavier than the proton. As you may already know, nucleons are made of quarks; protons (uud) and neutrons (udd) were the masses are 938.3 MeV and 939.6 MeV, respectively.
