Experimenting with Chemistry Irish Scientist Robert Boyle proved that air was not a basic element as it was made up of several gases. English chemist Joseph Priestly the existence of oxygen. France’s Antoine Lavoisier discovered the materials consume oxygen when they burn, discovering the nature of combustion.
