Niels Bohr created the planetary model of the atom, including the nucleus and electrons. This, however, is not the accurate model of atoms. It is said to be the electron cloud which is most accurate

There are numerous subdivisions of chemistry! The main areas would probably be: Inorganic, Organic, Physical and Analytical.
Niels Bohr, one of the main developers of quantum mechanics in the 1920s & 1930s.
Julian Banzon was a Filipino scientist whose main contribution to chemistry was the study he carried out into the use of alternative fuels. He advocated the use of renewable resources in fuel production.
Bohr's atomic model introduced some mechanical aspects to the atomic model, and, more importantly, it provided a theoretical frame for Rydberg's formula, which had been observed only empirically.
The Lydian's main contribution is that they invented the first coin.
