1922 he won a prize for his atomic structure. Also, he described how the atoms emit radiation.
1913 studied the reaction of light and atoms.
discovered that electrons move around the nucleus in circles.

discovered that electrons move around the nucleus in circles.
In 1909 he discovered the nucleus of an atom ( high density and positively charged).
His experiment was to aim a beam of small positively charged particles at a piece of gold foil and see where the light reflected to.
In the 20th century they explained more about electrons. They concluded that you cannot detect the path of an electron.
They came up with the theroy that electrons are more likely to be found in the “electron cloud”
In 1897 discovered there are small particles inside the atom, which means atoms can be divided into smaller parts.
Discovered electrons(negatively charged particles.
in 1803 he published his theroy that all substances combine in the same proportions because they are made up of one atom.
He thought that all substances are made of atoms, atoms are small and can not be destroyed created or divided.
Also that atoms combine to create other substances.
In 440 B.C. he thought that if you kept splitting an atom, the piece could not be split any smaller at some point.
He said that atoms are small and hard, they are also made of one material formed into different substances.
