1754/Scottish medical student Joseph Black discovered Carbon Dioxide Made people realize the third stage of matter "Gas"
1669 / German alchemist named Hennig Brandt find Phorphus in Urine
1767 / Priestley discover the making of "bubbly water"
1772/ Priestley had invented a better method: generating carbon dioxide and injecting it directly into water. This is Carbonation
Mid-1700s Phlogiston became popular.
Easter 1775/ Lavoisier announce his finding Oxygen. Without crediting Priestly
Oct. 1772/ Lavoisier set out to solve the riddle of why metals gain weight when they form calxes.
1772/ French Spy Magellan alerted France about British's interest for Soda Water as cure. Trudaine order Lavoisier to repeat the experiments
Aug 1774/ Priestly first contacted Oxygen But he was unable to explain it.
Sometime in 1774/ At a chemist gather,Priestly told Lavoisier about his discovery of Oxygen.
1789/ Lavoisier publish his chemical theory. Phlogiston theory slowly deceased.
1799/ Davy overthrown Lavoisier's theory of heat. He argue heat was motion of particle.
1799/ Davy discover Nitrous Oxide.
1800/ Alessandro Volta announced his invention "voltaic pile"the first battery.
1807/ Davy isolated potassium,sodium,magnesium, calcium, strontium, and barium.
1868/ Mendeleev completed the first volume of Principles of Chemistry
1869/ Mendeleev published the first version of Periodic Table of the Elements. Setting up the periodic law.
1873/ The founder of gallium,a french chemist, question the periodic law. The density didn't match Mendeleev’s prediction. Mendeleev suggested that he check his data. The french chemist recheck his measurement only to prove Mendeleev was correct.
1894/ the newly found element Argon didn’t seem to fit into the table. Challenging the Periodic Table.
1902/ the family of noble gas, helium, neon, argon, krypton and xenon, were added to the periodic table by Mendeleev.
1895/ Discovery of X-Ray
1902/ Marie Curie discover pure Radium and a new property of matter "radioactivity".
July 1898/ Marie Curie discover Polonium
1789/ discovery of uranium by Martin Heinrich Klaproth
Early 1770s / Joseph Priestley discovers many gases elements
Lavoisier study air in depth. Discovering alloy. Abolished ancient elements-air,water,earth,and fire and Phlogiston Theory. Many Chemist around the world refused to abandon the old theory.
New discover krypton, xenon and neon doesn't fit in periodic table.
