Ernest Rutherford conducted this famous Gold-foil experiment - well he supervised Marsden and Geiger performing it which lead to the planetary model of the atom.
The center of an atom is a nucleus. In the center of the nucleus, there is protons and neutrons. Around the atom, is the shell. Using the shell, as an orbit is the electron.
In 1911, Rutherford decided to experiment using what was the current theory of atomic structure at the time. Based on his results, he proposed a new theory; that the majority of the atom is empty space, and that all of the positive and most of the mass are contained in a small central region within the atom, which became later known as the nucleus.

Charles Darwin and his son did an experiment in 1880 using grass plants which led to the discovery of phototropism, this discovery led to many other scientists wanting to find out other tropisms
A scientists should form a hypothesis, then conduct an experiment.
Peroxisomes, Lysosomes, E.R., and the Golgi Apparatus.
Ernest Rutherford suggested that most of the mass of the atom is located in the nucleus. He came to this conclusion after finding the results on his famous gold foil experiment. This is where he fired radio active particles through very thin metal foils, and detected them using screens covered in zinc sulphide.
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.

Robert Millikan discovered the electron's charge using the oil drip experiment. Eugene Goldstein discovered positive particles with the anode/cathode ray tube. James Chadwick discovered the neutral particle with the beryllium and paraffin wax experiment.
