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
Niels Bohr's main concern or question was how electrons can exist in specific energy levels around the atomic nucleus without radiating energy and collapsing into the nucleus, according to classical electromagnetic theory.
Jabir's major contribution in chemistry is the discovery of nitric acid and sulphuric acid. He prepared Aqua Regia (Royal water) to dissolve gold. by leo=)
The five main subdivisions of chemistry are analytical chemistry, physical chemistry, organic chemistry, inorganic chemistry, and biochemistry. Each area focuses on different aspects of matter and its interactions.
The 5 main things used in chemistry are change, Role of the Atom, Resonance, inductive effects and orbitals. These are used mostly.
One of the main defects of the Bohr atomic model is that it does not explain the spectra of atoms with more than one electron accurately. It also cannot account for fine details in spectral lines caused by interactions between electrons. Additionally, it does not incorporate the wave nature of particles, as described by quantum mechanics.
Niels Bohr, one of the main developers of quantum mechanics in the 1920s & 1930s.
Niels Bohr's main concern or question was how electrons can exist in specific energy levels around the atomic nucleus without radiating energy and collapsing into the nucleus, according to classical electromagnetic theory.
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.
The main contribution is the development of new theorem in the subject area

Masunaga was the founder of the Zen Shiatsu which was his main contribution to shiatsu.
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.
the federation of move was his main contribution
There actually three(3) branches . They are :- ORGANIC ; Chemistry of carbon compounds. INORGANIC ; Chemistry of non-carbon compounds (The rest of chemistry) PHYSICAL ; Chemistry involved, with heat , light, energy, calculations, stoiciometry.
