An isotope can be produced if a nucleus gains a neutron or if one of the protons in its nucleus decays into a neutron and positron.
Helium is produced
When atoms lose electrons cations are produced.
You add or remove one or more neutrons from each atom.
They can be, depending on the reactor design.
Isotopes of radon (Rn)
Thorium isotopes are obtained.
Thorium, radium, radon, polonium, thallium, etc.
From hydrogen, isotopes of helium are formed through nuclear reactions.
Isotopes are located within the nucleus of an atom. They are variants of a particular chemical element, having the same number of protons but different numbers of neutrons. Isotopes can exist naturally or be artificially produced.
Decay products of ununpentium are ununtrium isotopes.
New elements(or isotopes of decaying element) are produced and energy is released
Some common radionuclides that can be produced from tellurium-124 are Iodine-123 and Iodine-124.
