Pronunciation: [a͡ɪnstˈa͡ɪni͡əm] (IPA) 
Einsteinium is a radioactive metallic element with the atomic number 99, named after physicist Albert Einstein. Synonyms for einsteinium include Es, unnilennium, and element 99. It is a synthetic element that does not exist naturally in the Earth's crust. Einsteinium is primarily used for scientific research and has relatively few practical applications due to its high level of radioactivity and short half-life. It was first discovered in the debris of the first hydrogen bomb explosion on the Eniwetok Atoll in the Pacific Ocean in 1952. Einsteinium is an extremely rare element, with only a few milligrams being produced each year for research purposes.
