Element 117, discovered by Laboratory, one step closer to being named. Element 117, first discovered by Lawrence Livermor escientists and international collaborators in 2010, is one step closer to being named.
This group is also known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po). The synthetic element livermorium (Lv) is predicted to be a chalcogen as well. Often, oxygen is treated separately from the other chalcogens, sometimes even excluded from the scope of the term chalcogen altogether, due to its very different chemical behavior from sulfur, selenium, tellurium, and polonium.
