Dalton reintroduced the concept of the atom and created _____ which was the basic concept of the molecule.
He also proposed that all of the positive charge and all of the mass of the atom occupied a small space in the center of an atom and that most of the atom is empty space occupied by electrons (Historical …
HISTORICAL OUTLINE of the Atomic Theory and the Structure of the Atom . Development of the Atomic Theory . Democritus (460-370 BC) First proposed the existence of an ultimate particle. Used the word “atomos” to describe this particle. Democritus . Aristotle (384-322 BC) was a proponent of the continuum. He believed in the four elements of air, earth, water and fire. Aristotle felt that
Calculated that the atom consisted mostly of empty space through which electrons move and also concluded that there was a tiny, dense region “the nucleus” centrally located within the atom that contained all of an atom’s positive charge and virtually all of its mass.

Historical Development of Atomic Theory: Aristotle to Rutherford1. Democritus and Aristotle in 400 B.C.2. Aristotle: matter can be divided into smaller andsmaller particles.3. Democritus: the atom is the smallest unit.4. Aristotle’s theory was most popular.
For example, water is a compound made up of 2 atoms of hydrogen and 1 atom of oxygen (a ratio of 2:1). Three atoms of hydrogen and 2 atoms of oxygen cannot combine to make water. Three atoms of hydrogen and 2 atoms of oxygen cannot combine to make water.

a Historical Perspective Early Greek Theories 400 B.C. – Democritus thought matter could not be divided indefinitely. John Dalton 1800 -Dalton proposed a modern atomic model based on experimentation not on pure reason.
3 John Dalton (1766 – 1844) father of the atomic concept. The main points of Dalton’s atomic theory were: • Elements are made of extremely small particles called atoms.

Chemistry: Development of the Atomic Theory. STUDY. PLAY. More than 2000 years ago, Greek philosophers proposed the existence of very small, indivisible particles, each of which is called an . atom. The theory that such particles existed was supported, much later by , who proposed, in his law of , that matter can’t cannot be created or destroyed. Lavoisier Conservation of matter. Then Proposed
