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 ...

In 1913, Niels Bohr, along with Ernest Rutherford, presented a model of the atom, suggesting it to be a dense nucleus surrounded by orbiting electrons. Though this "Bohr model" of the atom is now ...

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 ...

Atoms have a central positive nucleus. Most of the mass of an atom is found in the nucleus. 1913 Bohr In-depth work on Rutherford's model showed it had limitations. The electrons should just ...
