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.
When a nucleus has too many protons, it can undergo a process called electron capture where it absorbs an inner-shell electron to convert a proton into a neutron. This process helps to achieve a more stable nuclear configuration by decreasing the proton-to-neutron ratio.
I'm not sure there's a word for it. Ones with fewer neutrons might be "neutron-deficient" (or "neutron poor"), though a) that's probably politically incorrect and b) I think it refers to nuclei that have less than the optimal number of neutrons, even if it isn't actually less than the number of protons.
electrons. the atom either gains or looses electrons to become negatively or positively charged. An ion can also be formed by the addition or subtraction of a neutron.
An oxygen ion with a charge of -2 has 8 protons, 10 neutrons, and 10 electrons. The number of protons and neutrons remains the same as a regular oxygen atom (8 and 8, respectively), but the number of electrons increases by two to accommodate the charge.
A "neutron ion" doesn't exist.

Ion.
A neutron has no charge, so a charged atom (ion) cannot attract a neutron.
A neutron, which has neutral charge
A neutron. Negatively charged ion?
electron is the smallest
Hydrogen H+ ion is (i.s.o. 'can be thought of as ...) one proton.
no
Mg+2 and Br-1
The lithium ion is essentially the same as the lithium atom, except it has lost 1 electrons. The number of protons and neutrons remain the same. Thus, the lithium ion, Li+ has 3 neutrons, just like the lithium atom.
In a normal hydrogen atom, not an ion or an isotope, there are two particles in the nucleus - one proton, one neutron - and one electron circling it. Of course, if it were a positive ion there would be one proton and nuetron, but no electrons.
