Here are the postulates of Dalton’s atomic theory. Matter is composed of exceedingly small particles called atoms. An atom is the smallest unit of an element that can participate in a chemical change.
WebDalton’s Atomic Theory also suggested that an atom is the smallest part of an atom that can take part in a chemical reaction. Some postulates of this theory remain valid even in today’s modern chemical thoughts. The atomic structure model proposed by indeed proves to be a significant, stepping stone in chemistry.
