Bohr’s Model of an Atom: Danish Physicist Niels Bohr received his Ph.D. from the University of Copenhagen in 1911. In 1922, he was awarded the Nobel Prize in Physics for his work on the atom’s ...

Everyone at that time imagined the atom as a "plum pudding ... planets around the sun. In 1912 Bohr joined Rutherford. He realized that Rutherford's model wasn't quite right.

For example, according to classical physics, the electrons orbiting the nucleus should lose energy until they spiral down into the center, collapsing the atom. Bohr proposed adding to the model ...

Therefore, electrons cannot be arranged at random, but they must have fixed levels of energy within each type of atom. Bohr's 'solar system' model of the atom is the way that most people think ...

The Danish physicist Bohr had already, by this time, released his model of the atom. His model was inspired by a theory first put forth by Max Planck in 1900: that energy is emitted or absorbed as ...

The New Zealander had discovered the atomic nucleus in 1911 and further investigations by Bohr led to his quantum model of the atom where electrons travel around the nucleus in certain orbits. When ...

The Standard Model of particle physics explains ... particle and wave-like properties. In 1913, Neils Bohr proposed that electrons in an atom orbit the nucleus in discrete energy levels.
