The chemical symbol for ununpentium is Uup. However, it's important to note that ununpentium is now known as moscovium (Mc). This element, which has the atomic number 115, was officially named in 2016 and is classified as a synthetic element in the p-block of the periodic table. Moscovium is produced in particle accelerators and has a very short half-life, making it highly unstable and difficult to study. Its discovery is significant in the field of nuclear chemistry and helps scientists understand the properties and behavior of superheavy elements in the periodic table.
