500 BCE
The Alchemists
They were men who developed a theory that every single metal is composed of mercury and sulfur and it is possible for it to change the base metals to gold. -
427 BCE
Plato
He was best known as a Disciple of Socrates because he worked on his own atomic theory. He broke down the elements to: fire, air, water, earth and which are known as Platonic Solids. -
400 BCE
Democritus
He figured out that any kind of material is made up of smaller things. Just like how matter cannot be created nor destroyed. His idea lead to be a modern theory and he was the first to create any type of atomic theory. -
384 BCE
Aristole
He was a Greek Philosopher who invented the field of formal logic. His theory was spread world wide for many years and it was an alternative for Modern Physics. -
Robert Boyle
He did physical experiments to see if his studies were right about gases. He also wrote science and morality books about his past studies on gases. -
Antoine Lavoisier
Antoine was well known for his experimentation skills. he came up with the Law of Conservation by using his formula of HgO into Hg+O. The Law of Conservation states that matter can not be made or destroyed. -
John Dalton
He is known for introducing the atomic theory into chemistry. All atoms that are apart of the elements are identical. Matter that is built up to make atoms that are indivisible and indestructible. He invented the Solid Sphere of "Billiard Ball" Model. -
Dmitri Mendeleev
Dmitri was a Russian Chemist who invented the Periodic Table. He placed all of the elements together in their atomic number with similar properties. -
The Curies
A lady named Marie Curie discovered that the atoms arrangement did not lead to them being radioactive. She also discovered Polonium and Radium they are elements that decay slowly and it is a chemical that is highly radioactive and it has no stability. -
Ernest Rutherford
He is known to be the father of nuclear physics. He figured out that gases can rise from radioactivity. For example helium can be produced by using radioactive substances. -
Albert Einstein
Albert was a scientist and a physicist. He was so smart that he was known as the Creator of the Special Theory's. -
Henry G.J. Mosely
He was an English physicist who discovered the atomic number. His discovery of the atomic number has helped organize the periodic table by having the elements in order based on there physics. -
Neils Bohr
A electron is only allowed to orbit certain areas around the nucleus. It depends on the size of the energy because the lowest energy is found in the smallest orbit. He invented the Solar System Atom Model. -
Robert Millikan
Robert did a series of experiments that determines the electric charge that is moved by a single electron. He discovered the electron charge with an experiment that he did with oil and the effect was a cosmic radiation. -
Werner Heisenberg
He created a formula that deals with quantum mechanics based on matrices. The quantum theory is they study of particles that are smaller than an atom and how they interact with each other. He invented the Electron Cloud of "Billiard Ball" Model. -
J.J. Thomson
He invented Plum Pudding and he discovered the atomic nucleus. The name Plum Pudding is from the electrons that are negatively charged particles and atoms that do not have an electric charge.
