Moscovium is a synthetic element with the atomic number 115. It was first created in 2003 by scientists in Russia and the United States, and it is named after the Moscow region, where part of the discovery took place.
Because it doesn’t exist naturally and breaks down very quickly—within milliseconds—Moscovium can only be studied in controlled laboratory conditions. It belongs to group 15 on the periodic table, alongside elements like nitrogen and bismuth, but its extreme size and short lifespan mean its chemical properties are mostly based on predictions.
Even though we can’t observe it directly in large amounts, Moscovium helps scientists explore how the heaviest atoms behave, and how the structure of matter might change at the farthest edge of the periodic table.
