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 ...
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.
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 ...
When an electron dropped from a high-energy orbit to a lower-energy one, it gave out light with an energy equal to the ...
The atom is a complex system of particles ... Chemical reactions result from interactions between the electrons in two atoms.

Many stable atoms have ‘magic numbers’ of protons and neutrons − 75 years ago, 2 physicists discovered their special propertiesThe 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 ...
