-adopted the name Paracelsus
- wasn't afraid to challenge the orthodoxy of the day
-suggested that the world was made in 3 elements, salt,sulfur and mercury ; " core ingredients for making metals and medicines" -
16th century
Alchemists began to penetrate substances around them in their bid to turn base metals into gold -
Robert Boyle
-Studied phosphorus
- wrote the "Skeptical Chemist"
- one of the founders of the royal society
- opened up the scientific method and helped alchemists be considered as chemists -
Johann Becher
- a year after the Great Fire of London he suggested that the fire was caused by pholgiston, a substance that was colorless, tasteless, odorless and weightless was caused the fire.
-
Henry Cavendish
- discovered hydrogen
-
Hennig Brandt
- was looking for a way to extract gold from the body which was urine -instead he discovered the element phosphorus
- he called it "Icy Knock Toluca" -It is used in drugs to promote bone growth in people with osteoporosis
-
Joseph Priestley
-Invented the fizzy drink
-discovered oxygen -
Antione Lavoisier
-proved that Joseph Priestley's experiment was oxygen not phlogiston
- renamed 33 elements
-first scientist to define an element -
Humphry Davy
discovered force of electricity to rip apart a caustic chemical called potash and discovered a new element called potassium -
Robert Bunsen
Invented the Bunsen Burner -
Gustav Kirchhof
Invented the Spectroscope, an instrument made from two telescopes, a wooden box and a prism. -
Discovery of Rubidium,Cesium, Thalium and Indium
Bunsen and Kirchhoff discovered these element by using the Spectroscope and Bunsen Burner. Wavelengths were measured for every element which were all different. -
Discovery of periodic table
Russian chemistry professor, Dmitri Meneleev created the periodic table -
Article of 3 missing elements of Periodic Table
Mendeleev published an article making predictions about three missing elements based on the properties of their neighbors -
Discovery of Aluminum
French chemist found a new metal called aluminum -
Discovery of Argon
Two british scientists found a new gas called Argon that didn't seem to fit in the periodic table -
Isolation of Helium
William Ramsay isolated helium after 30 years and also said it had no place in the periodic table -
Discovery of Krypton, Xenon and Neon
William Ramsay discovered these three new gases -
Marie Curie discoveries
Marie made two discoveries. She found that the element thorium could make air a better conductor.That was the real solid indication that this was not unique to uranium this might be a property of matter not curiosity and pitchblende seem to be radioactive -
Discovery of Polonium
Marie Curie and Shelton T. Murray announced the discovery of Polonium. Fun fact: the element is named after Marie Curie native country, Poland. -
Many elements were discovered in the 19th century

Spectroscopy was a "Golden Standard"
It was the golden standard of identifying elements in the 1900s -
Isolation of Radium
Marie Curie and her husband successfully isolated one tenth of a gram radium from ten tons of pitchblende residue. -
First Female Scientist

Marie Curie for Nobel Prize again!
She was rewarded a Nobel Prize for chemistry in recognizing radioactivity -
Madame Curie 1943 film
The film "Madame Curie" showed how tirelessly she worked to seperate the radium from the pitchblende residue
