The Atomic Theory Timeline By:Genesis Turner

Was born in Paris France December 15, , he entered the Polytechnic. 1874, entered the government department of Ponts-et- Chausses. Henri later discovered radioactivity in 1896 Importance:

Ernest Marsden was an English Physicist born in East Lancashire, living in Rishton and educated at Queen Elizabeth’s Grammar School. Attended the University of Manchester where he conducted the famous experiment called the gold foil experiment with Hans Geiger. Served in France as a Royal Engineer in World War 1 and earned the Military Cross. Later discovered the Atomic Nucleus

A Danish physicist who was generally regarded as one of the foremost physicist of the 20 th century First to apply the quantum concept which restricts the energy of a system to certain discrete values. Importance:

Was appointed Lecturer in Theoretical Physics at the University of Copenhagen under Niels Bohr in 1926 and in 1927 was appointed Lecturer in Theoretical Physics at the University of Leipzig. His new theory was based only on the radiation emitted by the atom. Stated his famous principle of uncertainty, which lays its down that the determination of the position and the momentum of a mobile particle necessary contains errors the product of which cannot be less than the quantum constant (H)

Was a Greek natural philosopher from ( B.C) who promulgated the atomic theory, which asserted that the universe is composed of two elements ( the atoms and the void in which they move). Importance:
