The Elixer of LIfe Creates Further Interest in Chemistry
Alchemists propose the possibility of a drink to make a person immortal, making even more people take an interest in the old ways of chemistry. -
Period: to
Lavoisier Becomes the Father of Modern Chemistry
Antoine Lavoisier identifies and names both oxygen and hydrogen, as well as helps to form the metric system, creates the first extensive list of elements, reformed chemical nomenclature and disproved Phlogiston Theory. -
Dalton Revolutionizes Atoms
John Dalton writes and creates the first Atomic Theory, stating that all matter is composed of atoms which are tiny and indivisible. He thought they were jus tiny particles with no individual parts. -
The First Cathode Ray is Made
Michael Faraday passes an electric current through rarified air and discovers cathode rays, creating many new fields of research and discovery for chemists everywhere. -
Thomson Makes Subatomic Particles a Reality
J.J. Thomson suggests a particle 1000 times smaller than an atom, suggesting the first subatomic particle. He later proved this by discovering electrons and neutrons, also leading to the confirmation of isotopes. He saw the atom as a tiny particle containing the electrons and neutrons within it. -
Marie Curie Puts the Active in Radioactive
Maie Cyrie begins experimenting with radioactive materials, eventually dicovering a new and highly radioactive material, Polonium. -
Rutherford Takes His Turn to Attempt the Perfect Atom
Rutherford begins tests with alpha radiation and proves the existence of protons. He saw the atom as an encasement of the protons balancing the electrons and the neutrons being attracted in with radioactive force. -
Bohr Finally Works Out The Kinks in the Atomic Theory
Bohr proposes and proves that electrons are in constant orbit around an atom, and that they move in tiers that increase outwardly, the number and level of the electrons determining the energy an atom has. -
The Manhattan Project Takes Wing
Albert Einstein and Enrico Fermi warn the U.S. of Germany's tests with fission and kickstart a nuclear arms race, creating the first fission reactor, splitting atoms and the nuclear bomb.
