Robert Boyle
In the 1660's Robert Boyle experimented with the behaviour of gases, He was interested in what happened when gases where placed under pressure. He was also interested in determining the composition of gases and other substances -
Antoine Laurent Lavoisier
He developed a system for naming chemicals. naming some of the substances like Hydrogen, Oxygen and carbon. He was called "the father of modern chemistry" -
John Dalton
He used the observations from his experiments to develop his own theory of the composition matter. he suggested that all matter is made up of particles. he also explained that pure substancesd are made up of only one substance, i.e. Oxygen, Hydrogen, Chlorine. He invented the "Billiard ball" theory -
Matter today
