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.
one website said 10 but one said he had 3 kids...
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.
Yes. Crookes was knighted in 1897, and in 1910 received the Order of Merit.
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.
That the mass of an atom is mostly located in a small nucleus.
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.

Sir William Crookes died on April 4, 1919 at the age of 86.
Sir William Crookes was a British chemist who contributed to the knowledge of chemistry. One thing he did was discover an element that had a bright green emission line in its spectrum. He named the previously unknown element thallium.
no he was white
The Crookes' Tube
Sir William Crookes was born on June 17, 1832 and died on April 4, 1919. Sir William Crookes would have been 86 years old at the time of death or 183 years old today.
William Crookes received his name from his parents at birth. It's common for individuals to inherit their names from their families as a way to carry on a family legacy or honor a relative.
William Crookes was a British scientist who studied spectroscopy and cathode rays. He made significant contributions to the fields of chemistry and physics, and is best known for his discovery of thallium and for his work on vacuum tubes.
