He said that electrons are able to jump from energy levels to another but are not able to exist in the space in between.

Common substances broke down into the same elements

various compounds were a combination of atoms of different elements back of a particular size and mass

In 1826 Erwin made the electron "cloud" structure. He created the Schrödinger wave equation) that helps explain the movement of the electrons. Werner Heisenberg was born is Wurzburg is 1901. In 1926, when he was 26, he used a microscope to measure the momentum from an electron.

-Discovered the Electron in 1897
-Won the 1906 Nobel Prize for his discovery.
-Taught Earnest Rutherford and Neils Bohr.

Showed that common substances broke down into the same element in the same proportions

He fired a stream of tiny particles of positive charges at a thin sheet of gold foil
His used the gold foil experiment to conclude that atoms were just empty space
He concluded that the nucleus is dense and consists of Protons and Neutrons

Rutherford's  model showed a tiny, dense, positively charged core called a nucleus. - @jakehongg

Rutherford was testing out Thompson's theory, and shot positively charged particles at a golden sheet. Most passed through, but some deflected or bounced back. He concluded that there was a large, dense, positively charged nucleus surrounded by empty space, with the electrons surrounding the empty space.

Discovered there are smaller particles inside the atom, so the atom can be divided into even smaller parts. He proposed that there are negatively charged particles inside every atom known as electrons. He created the Plum Pudding Model.

# data[].attributes.body
He was the first to discover electrons. He ran test and he found out that gas gives off a negative charge. (These are known as electrons) He demonstrated this by using plum pudding.

Episode 3 of In Search of Giants: Dr Brian Cox takes us on a journey through the history of particle physics. In this episode we learn how Ernest Rutherford conducted a historical experiment that revealed that most of the mass of an atom is concentrated in a tiny nucleus made of protons and neutrons.
