Current atomic theory model
Webatomic theory. , first stated by John Dalton, an English scientist, in 1808. It consists of three parts: All matter is composed of atoms. Atoms of the same element are the same; atoms of different elements are different. Atoms combine in whole-number ratios to form compounds. These concepts form the basis of chemistry. WebSep 16, 2024 · Download Post as PDF. An atom is the smallest particle of every element. The word atom came from the Greek word Atomos which means indivisible. Atoms are made of electrons, Protons, and Neutrons. Protons and Neutrons reside in the nucleus of the atom and electrons orbit the nucleus. Atoms always have an equal number of …
