The International Union of Pure and Applied Energy announces the names of four new elements.
The International Union of Pure and Applied Energy (IUPAE) disclosed the proposed names of four new chemical elements, and one is named after the city of Moscow. 
 
The symbol, Mc, will denote the element with an atomic number of 115. It was discovered at the Joint Institute for Nuclear Research outside of Moscow with the help of the Dubna Gas-Filled Recoil Separator, and the heavy ion accelerator capabilities of the Flerov Laboratory of Nuclear Reactions.
 
Scientists proposed the name in accordance with recently revised IUPAE guidelines that urges using five categories when creating names: a mythological concept or character; a mineral substance; a place; a property of the element; or a scientist's name.
 
The proposed names for the three remaining elements are Nihonium, Tennessine and Ogannesson. The latter is in honor of Yuri Oganessian, a Russian nuclear physicist of Armenian heritage who served as head of the Flerov Laboratory of Nuclear Reactions, which is a branch of the Joint Institute for Nuclear Research, where the discovery was made.
 
The proposed names are open to public review until November 8 when the IUPAE council will make a formal and final decision. Those interested may contribute their input on IUPAE’s website until the deadline expires.
