Labels:text | screenshot | font | number OCR: NUCLEUS (ATOM) .............................................. THE POSITIVELY CHARGED dense region at the core of an atom is known as its nucleus. It is composed of positively charged protons and neutral neutrons (except for hydrogen nuclei which each consist of a single proton) and is circled by negatively charged electrons. The number of protons in an atomic nucleus determines which chemical element that atom is an example of.
