The current atomic theory

WebTimeline Description: Atomic theory is the scientific theory of the nature of matter. The theory states that matter is made up of small particles called atoms. Prior to this theory, matter was thought to be able to be divided into any small quantity. The word atom is derived from the Greek atmos, meaning indivisible. WebThe modern (current) theory of atomic structure states that the electron is treated as both a wave and a particle. The result is the Schrodinger Wave Equation, a mathematical …
