-
The first person to develop concept of an atom. He was influenced by Socrates and taught Aristotle. -
Made the theory that all material bodies are made up of individually small atoms. He wrote over 70 treatises. -
They Believed that there were 7 base elements. They guarded their work in secrecy. -
He demonstrated matter is made of tiny particles. He helped found the Royal society in England. -
Illustrate relative positions and motions of planets, and moons in the solar system. -
He named the elements of carbon, hydrogen, and oxygen. Also, he discovered oxygen's role in combustion. He helped us understand the law of conservation of mass. -
Also known as the atomic model, which is a representation of the atom, like describing structure of the atom. -
He proposed that all matter is made of indestructible unchangeable atoms. He calculated the first relative weight of atom. -
He proposed that atoms of elemental gases may be joined together in molecules rather than being separate. He also discovered equal volumes of gasses contain equal number of molecules. -
He made the periodic table. He also predicted the elements of scandium, gallium, germanium. -
He discovered the electron. In 1906, he won the Nobel prize for physics. -
They researched into radioactivity. Discovering radium and plutonium. A unit of radioactivity is called a curie. -
A Historical, Scientific model of a atom. -
He proved the existence of atoms mathematically. He couldn't speak until he was 4 years old. -
He made an accurate determination of the charge carried by an electron. He had a Nobel prize in physics in 1923. -
He proved that all the positive charge in the atomic nucleus was contained in a volume 1/100,000 the size of an atom. The atom Rutherfordium 104 was named after him. -
He proposed a model of an atom in which electrons resolve in stable orbits around the nucleus. -
He redefined the idea of atomic numbers rearranged periodic table based on it. Determining charges on nucleus of most atoms. He also created the concept of the atomic number. -
He proposed Quantum Mechanical Model. That treats electrons as matter waves. -
Model of an atom that shows the most probable positions of electrons. -
He discovered the neutron. His father was a cotton spinner, and he is the youngest of 3.
