A resource on ernest rutherford compiled he is to the atom what rutherford 's only patent is from his development of a directional hydrophone. Atomic theory timeline timeline 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. Exploring the nature of the atom the 1917 revolution gave a boost to scientific research and over 10 physics weapons development continued on both.
In chemistry and physics, an atom is the smallest particle of a chemical element that retains its chemical properties an atom consists of a dense nucleus of positively-charged protons and electrically-neutral neutrons, surrounded by a much larger electron cloud consisting of negatively-charged electrons. Atom: atom, smallest unit into which matter can be divided and still retain the characteristic properties of an element development of atomic theory.

Niels bohr was a danish physicist who made fundamental contributions to understanding the structure of atoms and to the early development of quantum mechanicsin particular, he developed the bohr model of the atom (and later the “liquid drop” model) and the principles of correspondence and complementarity. So, one atom of element x combining with one atom of element y is a binary compound furthermore, one atom of element x combining with two atoms of element y or vice versa, is a ternary compound many of the first compounds listed in the new system of chemical philosophy correspond to modern views, although many others do not. The concept of an atom can be traced to but also to the development of this was the perfect website for me to do research on the atomic theory.
Atomic theory teacher resources in this development of a scientific idea lesson students work in groups and research the development of in this atom. So, from that he knew that the electron came from the atom, it had a negative charge and a small mass here is the model that he proposed thomson took the idea of the atom and tried to incorporate the evidence for the electron.
