Abstract
... Elements are characterized by the number of protons and electrons, i. e., oxygen has eight protons and electrons. Atom core consists of protons and neutrons. It is common that atom core contains variable number of neutrons and constant number of protons. In the case of oxygen, three types of cores a ...
