Niels Bohr change the atomic theory by realizing that the electrons did not crash into the nucleus as would be expected in classical physics. In particular, he developed the Bohr model of the atom (and later the “liquid drop” model) and the principles of correspondence and complementarity. Niels Bohr was a Danish physicist who made fundamental contributions to understanding the structure of atoms and to the early development of quantum mechanics. ![]() What contributions did Niels Bohr make to study of an atom? In the model he created, an electrons energy is determined on how far away the energy level is from the nucleus. He proposed that an electron is found only in circular paths or orbits around the nucleus. Niels Bohr came up with the revolutionary theory on atomic structures. What did Bohr introduce to atomic theory with his model? Unlike earlier models, the Bohr Model explains the Rydberg formula for the spectral emission lines of atomic hydrogen. The Bohr Model contains some errors, but it is important because it describes most of the accepted features of atomic theory without all of the high-level math of the modern version. Why is the Bohr model important to the atomic theory? While all atoms of an element were identical, different elements had atoms of differing size and mass. What did John Dalton contribute to the understanding of the atom?ĭalton’s atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. ![]() This theory led to the modern understanding of atoms. John Dalton was a chemist who made many contributions to science, though his most important contribution was the atomic theory: matter is ultimately made of atoms. Who made the most significant contribution to the atomic theory? ![]() He also theorized that electrons move in definite orbits around the nucleus, much like planets circle the sun. He built on the concept that the mass of an atom is contained mostly in the nucleus. In 1913, the Danish scientist Niels Bohr proposed an improvement. What did Bohr contribute to the atomic theory apex? Because the ratios were the same, Dalton was able to say that atoms of different elements combine in whole number ratios. Thompson, Ernest Rutherford, Niels Bohr, James Chadwick and Ernest Schrodinger each contributed greatly to the modern atomic theory by finding the actual evidence. What was their contribution to atomic theory? Bohr was the first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element. The Bohr model shows the atom as a small, positively charged nucleus surrounded by orbiting electrons.
