Democritus was born
He lived in abdera -
400 BCE
Democritus’ Discovery (unknown date)
Democritus discovered that all matter consisted of tiny, invisible particles. How- he pounded materials until he made them into smaller parts and then made his conclusion Theory - atoms are always moving, they’re made of a single material, and formed by materials joining together -
370 BCE
Democritus died
R.I.P -
Antoine Lavoisier was born
He was born and lived in Paris, France for most of his life and (fact) he was known as “The Father of Modern Chemistry”. He was also born into a wealthy family -
John Dalton was born
He lived in the United Kingdom and (fact) he was colorblind but it was never confirmed until 1995 -
Antoine Lavoisier’s Discovery
He discovered that atoms are neither created nor destroyed. How? Well he studied chemical reactions and experimented some on his own. -
Antoine Lavoisier discovered Oxygen
-
Antoine Lavoisier discovered Hydrogen
-
Antoine Lavoisier died

John Dalton’s Discovery
Matter is made up of atoms that are invisible and indestructible. He also created the first chart of atomic weight. How? He experimented with glasses which led him to his conclusion. -
John Dalton died
-
J.J Thomson was born
He lived in the United Kingdom and (fact) married one of his students -
Max Planck was born
He lived in Germany and (fact) was a great musician -
James Chadwick was born
He lived in the United Kingdom and (fact) was a prisoner during World War I -
Marie Curie was born
She lived in Poland and (fact) both her parents were teachers. -
Robert Millikan was born
He lived in the United States. -
Ernest Rutherford was born
He lived in the United Kingdom (fact) but he was born in New Zealand. -
Albert Einstein was born
He was born in Germany but lived in New Jersey the majority of his life. -
Niels Bohr was born
He lived in Denmark and (fact) played soccer on the college soccer team. -
Erwin Shrödinger was born
He lived in Austria the majority of his life. -
Louis De Broglie was born
He was born and died in France. -
JJ Thomson’s Discovery
He discovered the electron. How? He experimented with a cathode ray tube. -
Marie Curie’s Discovered Radium and Polonium
How? She isolated radioactive radium salts and discovered the existence of the two new elements. -
Werner Heisenberg was born
He lived in Germany his whole life. -
Albert Einstein’s Discovery
He discovered about atoms in a liquid. They’re much different than atoms in a solid. How? He used the mathematical brownion motion. He also created a formula, and foreshadowed creating the atomic bomb and power. -
Robert Millikan’s Discovery
He discovered the charge of an electron. How? He preformed the oil drop experiment high helped quantify the charge. -
Ernest Rutherford’s Discovery
He created the Rutherford model, which is a model of the atom proving thomsons model wrong. How? Atoms have small charged neutrons surrender by space and circled by electrons. With that information, he created the correct model. -
Niels Bohr’s Discovery
He discovered the hydrogen atom. How? He used the quantum theory and a lot of experimenting. -
Max Planck’s Discovery
He originated the quantum theory which helped understand atomic and subatomic process. -
Louis De Broglie’s Discovery
He discovered that electrons have a wave of nature. Or in other words the wave nature of electrons. How? He used the quantum theory. -
Werner Heidenberg’s Discovery
Werner discovered the Theory of quantum mechanics, and the discovery of allotrope forms of hydrogen. How? He mainly researched and used the quantum theory. -
Erwin Shrödinger’s Discovery
He took the Bohr atom model one step further and cleaned up the model. By stating that electrons are constantly moving, they never stay in one spot or position. How? He used mathmateical quations and the quantum theory. -
James Chadwick’s Discovery
He discovered the neutron. How? He bombarded beryllium atoms with alpha particles. An unknown radiation was produced which became neutrons. -
