An ATOM is the smallest build block of MATTER that can EXIST and is composed of a central core NUCLEUS that is surrounded by NEGATIVELY CHARGED ELECTRONS. Within the NUCLEUS, an ATOM contains POSITIVE CHARGED PROTONS and NEUTRALLY CHARGED NEUTRONS. An ATOM has no charge and is considered NEUTRAL, such that are an EQUAL number of protons and electrons to provide an equivalent number of POSITIVE and NEGATIVE charges resulting in a net ELECTRICAL charge of ZERO. . . . . . . . . . #chemistry #atom #nucleus #matter #electron #proton #bohrmodel #bohr #electronconfiguration #prepineer #feexam #eitexam #orbitals (at UF Department of Chemistry)
