John Dalton - Particles
John was best known for 3 specific things. One was his pioneering work, the development of modern atomic theory, and last research for colour blindness. He had a fascination with gases got bigger and bigger. He investigated more into this and this led him to every form of matter either it be solid, liquid or gas
was made up of small particles.

J.J Thomson - Electrons & Subatomic Particles
Some awards Thomson has received was the Hughes Medal in 1902, Nobel Prize for Physics 1906, Copley Medal 1914 and the Franklin Medal 1922. J.J Thomson made the discovery and identification of the electron and the subatomic particle. In 1896 he went to America and gave four course lectures. During his time in 1905 he discovered the radioactivity in potassium

Marie Curie - Radium
Marie discovered polonium and the development of X-rays. Marie Curie also discovered radium (an element) in its pure state that spontaneously disintegrates into other elements. This proved that the atoms of one element at least were not indivisible. She also studied uranium and thorium and called the spontaneous decay of these elements "radioactivity." She later dedicated her time to working on x-rays.

Ernest Rutherford - Nuclear Physics
Ernest is known as the father of physics. He formed a theory that atoms have a charge in a nucleus in 1911. However he could not determine whether the nucleus was negative or positively charged. In 1917 he was also very widely credited for splitting an atom first in a nuclear reaction

Niels Bohr - Theory of Elelctrons
He discovered electrons in the interaction of alpha particles with a nucleus, and the theory of electrons that travel in orbits around the atom's nucleus. During 1913 in July, September and November, he created the Bohr model of the atom. This consists of a small nucleus with electrons orbiting around it.

Henry Mosely - Periodic Table
Henry Moseley studied at the University of Manchester. Henry is well known for creating the main basis of the periodic table and created a better order based on the atomic numbers. He is also very well known for the development of the x-ray spectrometry equipment. He was awarded with the nobel prize in 1916 for physics. Henry helped Niels Bohr with his first experimental evidence in Niels Bohr's theory.

Francis Aston - Isotopes
During Francis’ studies on his evidence on two isotopes, he was interrupted by the War in 1914-1918. In 1919 he went back to Cavendish Laboratory, where he then researched the separation of the isotopes of neon. With this he happily achieved the separation of isotopes of neon, with the help of his new invention of the mass spectrograph. Having succeeded what he planned he began to write. He wrote books called Isotopes and Structural Units of the Material Universe (1923).

Erwin Schrodinger - Electrons
In 1921 Schrodinger published his first article about the effect of the interaction of electrons on some features of the spectra of the alkali metals. He took the Bohr atom model to the next level by using mathematical equations to find an electron in a certain position.

James Chadwick
James Chadwick made a discovery in the field of nuclear science, he proved the existence od neutrons. He predicted the atom would have a neutron. He established that tyhe atomic number was determined by the number of protons and neutrons in an atom.

Murray Gell-Man - Quarks
Murray proposed a new level of elementary particles called quarks. These quarks were used almost like building blocks of protons and neutrons which helped explain complex chemical substances. He helped to lay the base of our understanding of the components that make up matter.
