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.
William Crookes used a device called a Crookes tube in his experiments. This was a sealed glass tube that contained rarefied gas and electrodes for producing cathode rays. The Crookes tube was instrumental in the discovery of cathode rays and contributed to the development of early atomic theory.
The element krypton was discovered in 1898 by Scottish chemist and physicist Sir William Ramsay, and English chemist Morris William Travers.
Argon was discovered by two scientists, Sir William Ramsay and Lord Rayleigh, in 1894. They noticed a discrepancy in the density of nitrogen extracted from the air, leading them to discover a new element, which they named argon.
a beam of electrons was first called a cathode ray.
The inventor of the cathode ray tube was Kalman Tihanyi. Tihanyi was a Hungarian physicist and inventor, born in Slovakia in 1897.

William Crookes discovered plasma in 1879 while conducting experiments with electrical discharge in gases. His work laid the foundation for the study of plasma in physics and chemistry.

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.
