In this installment in the history of atom theory, physics professor (and my dad) dean zollman explains how niels bohr built on the work of others to craft.
Mr bohr expanded on rutherford's theory (that the atom consisted of a positively charged nucleus with negatively charged electrons orbiting around it. Author: chihiro fukushima the evidence that bohr used to support his model of the atom successive ionization energies provide evidence for the existence of quantum. To draw a bohr model of an atom, first find the number of protons, neutrons and electrons in the atom from its atomic weight and atomic number after that, place the. Bohr atomic model : in 1913 bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus.

Quantum mechanics and the modern picture of the atom as we now know today bohr’s model of the atom was really an oversimplification of the way electrons truly. Let's stop and review for a moment what exactly is the bohr model of the atom the bohr model has the following features: 1) there is a nucleus (this was rutherford. This effectively disproved the notion that the hydrogen atom was the smallest unit of matter, and thompson went further to suggest that atoms were divisible.
