WebRutherford’s postulates are a set of four scientific statements that describe the behavior of atoms. They are: 1. The atom is the smallest particle of an element that has the chemical properties of that element. 2. The atom is composed of a positively charged nucleus and negatively charged electrons. 3. The electrons orbit the nucleus in shells. 4.
