inside the necules there are protons and neutrons on the shells or levels are the electrons
Electron capture is the absorption of an electron by an atomic nucleus if that nucleus is neutron poor. An electron is captured, usually from an inner electron shell of that atom, and it will convert a proton in the nucleus into a neutron. We know that a neutron is converted into a proton and an electron in neutron decay, so it might be looked at as something of an opposite nuclear reaction where a proton and an electron combine to form a neutron.
Neutron stars could form in places where there are high-mass stars. After the star runs out of fuel in its core, the core collapses while the shell explodes into the space as supernova. The core would then become a neutron star, it might also become a black hole if it is massive enough.
Proton - Nucleus Neutron - Nucleus Electron - Shell/Cloud/Orbit
Electrons (that too the valence electrons or electrons in the outermost shell / orbital) are involced in bond formation.

First of all there is no such thing a a valence neutron. However there are valence electrons.Valence electrons are the electrons of the outer most layer or shell called valence shell. Based on a Bohr diagram or Lewis structure you can see that Helium has 2 valence electrons.
you already partly answered your own question. Neutrons.
DEUTERIUM ,it is 2nd isotope of hydrogen atom .It contain one proton and one neutron in its nucleus and one electron in it outer most shell . It is also known as (heavy hydrogen)
Judy neutron
If an electron is released from the nucleus (and not from an electron shell) then it would have been emitted by a neutron in beta decay. In beta-minus decay, a neutral neutron emits an electron and an anti-neutrino and becomes a proton; in beta-plus decay, a proton emits a positron and a neutrino and becomes a neutron.
No. A neutron carries no charge.
There is no such thing as a "positive neutron" or a "negative neutron". A neutron is always neutral.
