{"id":31747,"count":2,"description":"Radium (\u00a0\/\u02c8re\u026adi\u0259m\/ ray-dee-\u0259m) is a chemical element with atomic number 88, represented by the symbol Ra. Radium is an almost pure-white alkaline earth metal, but it readily oxidizes on exposure to air, becoming black in color. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226, which has a half-life of 1601 years and decays into radon gas. Because of such instability, radium is luminescent, glowing a faint blue.\nRadium, in the form of radium chloride, was discovered by Marie Sk\u0142odowska-Curie and Pierre Curie in 1898. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and Andr\u00e9-Louis Debierne through the electrolysis of radium chloride in 1910. Since its discovery, it has given names like radium A and radium C2 to several isotopes of other elements that are decay products of radium-226.\nIn nature, radium is...","link":"https:\/\/www.skateboarding-lessons.com\/go\/tag\/radium\/","name":"Radium","slug":"radium","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/tags\/31747","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.skateboarding-lessons.com\/go\/wp-json\/wp\/v2\/posts?tags=31747"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
