How radium was named?
Radium was discovered by Marie Sklodowska Curie and Perre Curie (FR) in 1898. The origin of the name comes from the Latin word radius meaning ray. It is a silvery-white radioactive metal that reacts with oxygen and water.
It is an intensely white metal that quickly tarnishes to black in the presence of air. Interesting Radium Facts: Radium was discovered by Pierre and Marie Curie in 1898. They extracted the element from a sample of the mineral uraninite.
- One result of radium's intense radioactivity is that the metal and its compounds glow in the dark. When it is exposed to air, it reacts with nitrogen to quickly form a black coating of radium nitride. It reacts very vigorously with water to form hydrogen gas and radium hydroxide.
- Radon is a chemical element with symbol Rn and atomic number 86. It is a radioactive, colorless, odorless, tasteless noble gas. Its most stable isotope, 222Rn, has a half-life of only 3.8 days, making radon one of the rarest elements since it decays away so quickly.
- Polonium is a chemical element with symbol Po and atomic number 84. A rare and highly radioactive metal with no stable isotopes, polonium is chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbors in the periodic table: thallium, lead, and bismuth.
According to the Los Alamos National Laboratory, radium is used to produce radon gas, which is typically used to treat several diseases including cancer. Radium is an unstable element and undergoes several stages of radioactive decay reaching its end product of lead, according to New World Encyclopedia.
- Radium 223 is a mildly radioactive form of the metal radium. It used to be called Alpharadin and now has the brand name Xofigo (pronounced zoh-fee-go). Doctors use radium 223 to treat prostate cancers that have spread to the bones.
- Radium is the heaviest and most reactive element of the alkaline earth metals family. Radium is rare because of its high reactivity and short half-life. It is a part of the group of elements that appears after bismuth (Z=83) which are all radioactive and unstable.
- Radium now has few uses, because it is so highly radioactive. Radium-223 is sometimes used to treat prostate cancer that has spread to the bones. Radium used to be used in luminous paints, for example in clock and watch dials.
Radium was discovered by Marie Sklodowska Curie, a Polish chemist, and Pierre Curie, a French chemist, in 1898. Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it.
- Radium was discovered by Marie Sklodowska Curie and Perre Curie (FR) in 1898. The origin of the name comes from the Latin word radius meaning ray. It is a silvery-white radioactive metal that reacts with oxygen and water.
- Polonium was discovered in 1898 by Marie Curie while she was working in France. Polonium was the first element discovered by Curie and it was named after her birthplace, Poland. Curie was attempting to to explain why pitchblende (a form of the mineral uraninite) from Joachimsthal, Bohemia was radioactive.
- Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Radium is classified as an "Alkaline Earth Metals" which are located in Group 2 elements of the Periodic Table.
