Protons and neutrons that's it
A nuclear to thermal and radiant
Explanation:
Nuclear fission is the disintegration of the force that holds the nucleus of the atom together, creating two different but lighter nuclei.
In nuclear fission, it seeks to break the force of attraction or nuclear force that joins the protons and neutrons that form the nucleus of an atom. Neutrons without electric charge are used against the nucleus of the atom to produce enough excitation energy to deform the nucleus into two halves.
Element. Everything is else is a mixture, therefore not pure.
30% should be the percentage of oxygen if the total mass of fe2o3 is 160.
