The Discovery of Oxygen
Discovered by both Joseph Priestley and Carl Scheele, this atomic element the base for a ton of things. It's what we breathe, it's the air around us, and it is one of the biggest scientific discoveries of all time. -
The Atomic Theory
Discovered by John Dalton, he wanted to teach his students about the chemistry of atoms, so he devised a theory, the atomic theory, the relationship between atoms and elements -
Atoms Combine Into Molecules
Discovered by French scientist, Joseph Louis Gay-Lussac, he discovered that atom of a gas isn't just one atom when he combined two gases and realized that their volume doubled; discovering molecules -
Synthesis of Urea
Although it may not be a completely innovational discovery, it was still very important discovery. It helped scientist understand that you can make materials that used to be made by organic substances out of inorganic substances -
The Chemical Structure
The idea of the chemical structure was used to show the connection between atoms in a molecule. This was shown by the elemental symbol and lines. The only molecule that didn't follow this rule was Benzene, which was later shown to have a ring structure and helped other scientists discover of these ringed molecules -
Periodic Table and Elements
Created by Dmitri Mendeleev to help his students understand the meaning of the elements, its an arrangement of the elements in a table, which shows the connection between each element. He also predicted three elements with this table, and is now the basis for all chemistry -
Radioactivity
While discovering the source of strange UV rays, a couple scientists figured out that it was due to the source of Uranium. Today it's used for medical resources and energy. -
The Electron
Founded by J.J. Thomson, he discovered the movement of electricity found in a cathode ray tube, that did not follow the rules of an ordinary electrical atom -
Plastic
While trying to understand the cellulose of plants, a scientist discovered that this substance can be turned into more than what plants just use it for. He discovered polymer and it's now one of the most used substances today. -
Fullerenes
The newest discovery out of the ten, was discovered when a group of scientists discovered that when carbon atoms compress and form a new substance, it turns into a brand new material. This material is one of the strongest materials in the world
