By heating mercury and collecting the gas produced (oxygen) a scientist discovered the first gas or oxygen as they called it.
-
John Dalton theorizes that all matter is made of tiny particles. He calls these particles atoms after what an ancient greek philospher called them.
-
By combining chemicals a scientist accidentally synthesizes Urea. This was a big deal because it was the first time an organic chemical was created using inorganic chemical which proved that its all made of the same stuff.
-
Scientists learn that sometimes chemical bonds arange diffrently depending on the elements and bonds. Did not record the date so i made a guess.
-
When different elements were exposed to fire, a different light pattern was omitted. Using a type of scope scientists are able to distinguish different elements from each other using just the light they produce when burned. This allowed for new elements to be discovered using only light and allowed study of elements in space.
-
Dimitri Mendeleev arranges the known elements by atomic number and finds that they arrange themselves in a way that groups them by their properties. He predicts new elements using his table which are later discovered. His table is still used today in chemistry.
-
With electricity being so easily accessible scientists began using it in experiments. When one scientist applied electricity to potash he found that it formed potassium. The idea of adding electricity to a chemical or a reaction was then used by many scientists to discover new things. Also did not have a date for this one so guessed the date
-
It is learned that uranium releases particles constantly and that there are other elements that are forms of uranium that have lost enough protons to become a new element.
-
By exploiting the stringiness and strength of cellulose in plants plastics are created. Plastics become used to in almost everything after this.
-
Scientists discover carbon atoms that have bonded in a very strong way. They are the strongest possible molecule that can be formed.
