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 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 atom is a complex system of particles ... Chemical reactions result from interactions between the electrons in two atoms. In Bohr's model, if an electron orbit is not already filled, then ...
