jan 1, 1808 - John Dalton 1808 AD
Description:
John Dalton was the first to come up with the modern theory of atoms. He studied many gasses where he observed the pressure of gasses and their ability to form different substances. He discovered a measurable way of explaining these gasses in small number forms and made his own table of elements, which was expanded upon to the one we have today.Added to timeline:
