Democritus Interesting fact: Created first atomic model. Atomic model made in greek age.
Biography: Democritus was an ancient Greek philosopher.Democritus was born in 460 BC and died in 370 BC when he was He published over 70 books.Born to a family of wealth he had enough money to make many experiments. -

Ernest Rutherford
Rutherford changed Thomson's model in 1911 with his gold foil experiment in which he demonstrated that the atom has a tiny, heavy nucleus. Rutherford designed an experiment to use the alpha particles with radioactive atoms as an example of the atoms. -

Neils Bohr
Niels Bohr was born on October 7,1885. Bohr started getting into physics at a young age.He discovered the atomic theory in 1922.He got a nobel prize.
The atomic atom is a small positively charged nucleus surrounded by electrons that travel in circular orbits.Sort of like the solar system.The model is known as the bohr model. -
