Jacques Curie was a French physicist who was a pioneer in the field of radiation, discovering two new chemical elements. One is named after him and it is now called radium. There have been many people before and after Curie who have contributed to the field of Chemistry but he has made some of the most important contributions. He discovered what are now known as radioactive minerals which are used for various purposes including health care treatment, industrial by-products, and archaeological purposes. He discovered how radiation can be used to treat cancer. And he made advancements in separating radioactive elements from minerals. But he has also had a difficult personal life, including being attacked by an insane man who attempted to kill him twice. Jacques Curie died at the age of 69 because of pancreatic cancer. He got it after being exposed to radium which was contaminated with polonium. At the time he was working for the radium institute which was founded by Marie Curie and Pierre Curie. He had spent most of his adult life studying radioactivity and conducting research on radioactivity at his laboratory in Paris' Laboratory 28, which is now known as the Curie Institute. Jacques Curie was a prolific scientist. His major discoveries include the identification of three new elements: radium, polonium and radon. He was also one of the first to determine that the radioactive decay from uranium turned into lead, but his biggest contribution to science despite being a physicist is his work on radioactivity as a whole. He also made advancements in separating radioactive elements from minerals which led towards his discovery of radium and polonium. The University of Paris where he studied chemistry had a tremendous impact on his career as a scientist. Radium is a metalloid that has a radioactive component to it, which was discovered by Pierre Curie and Marie Curie. It is a yellow-orange element which has a half-life of 1.3 years. It was discovered in 1898 from uranium ore from mines in Africa. It is the only naturally occurring element with an atomic weight of over 100 grams that is not in a chemical bond. Radium's formula is Ra2+, and it has an atomic number of 88 which makes radium the heaviest naturally occurring element in nature besides iodine, at 91. Radium can be found in uranium ores, usually at 0.5-2% concentration, and occasionally higher than 20%. When radium decays, it changes into a gas called radon. Radon is a colorless gas which has a half-life of 3.8 days. It is an alpha particle emitter and can be found in the environments underground, including mines and caves where uranium is mined from. Radon's natural occurrence is very low but it can still be found in some places today. Radon can be found in concentrations of 0.09-1% near uranium deposits, 0.4-0. cfa1e77820
