Priestley and Lavoisier discovered oxygen. I think they burned magnesium and it got heavier. The
phlogiston theory (the theory that people believed about burning and combustion) could not answer this so they had discovered something. We now know that oxygen from the air is "extracted" when the magnesium is burned. the oxygen then combines with the magnesium and form magnesium oxide. So if you started with 24g of magnesium and burned it, you would end up with about 40g of magnesium oxide.

Sir William crooks and the atomic theory?
Sir William Crookes was a British chemist and physicist who made significant contributions to the field of atomic theory. He is best known for his work on cathode rays, which eventually led to the discovery of the electron. Crookes' experiments with cathode rays provided crucial evidence for the existence of subatomic particles and helped lay the foundation for modern atomic theory.
Did Sir William Crookes receive any awards?
Yes. Crookes was knighted in 1897, and in 1910 received the Order of Merit.
What was Crookes atomic model called?
The Crookes atomic model is known as the plum pudding model. It was proposed by Sir William Crookes in 1904 and suggested that atoms are composed of a positively charged "pudding" with embedded negatively charged electrons.
What did Rutherfords gold foil experiment help him conclude?
That the mass of an atom is mostly located in a small nucleus.
What did William crookes conclude from cathode rays?
William Crookes concluded from cathode rays that there was something more to an atom. Something that carried an electrical current. This was a mystery at the time. William Crooke's experiment helped pave the way for J.J. Thompson's discovery of the electron.
