Philipus Aureolus Theophratus Bombastus von Hohenhiem
-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"
Alchemists began to penetrate substances around them in their bid to turn base metals into gold
- wrote the "Skeptical Chemist"
- one of the founders of the royal society
- opened up the scientific method and helped alchemists be considered as chemists
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.
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
-Invented the fizzy drink
-proved that Joseph Priestley's experiment was oxygen not phlogiston
- renamed 33 elements
-first scientist to define an element
discovered force of electricity to rip apart a caustic chemical called potash and discovered a new element called potassium
Invented the Bunsen Burner
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 was rewarded a doctorate in France
Marie Curie for Nobel Prize
She was rewarded a Nobel Prize in Physics
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
