Subatomic particle is the total number of nucleons (neutrons and protons collectively). Chemistry concerns itself with how electron sharing binds atoms into structures such as crystals and molecules. Nuclear physics deals with how protons and neutrons arrange themselves in nuclei. The study of subatomic particles, atoms and molecules, and their structure and interactions, requires quantum mechanics. Analyzing processes that change the numbers and types of particles requires quantum field theory. The study of subatomic particles "per se" is called particle physics. The term "high-energy physics" is nearly synonymous to "particle physics" since creation of particles requires high energies: it occurs only as
Atomic Sub Noah Talbot was the Human Sub (though this was changed to the Atomic Sub after the war). After World War II, the Atomic Sub became a member of the Roundtable of America with Knight Watchman and Ultiman. During the Criss-Cross Crisis (In which Earths A and B came into contact with one another), The Atomic Sub bravely sacrificed himself to save the two Earths, and was respected as a hero on both worlds. In the distant future, the remains of the Atomic Sub were used to construct the cyborg known as Bezerker. As well as super-strength and flight, the Atomic
