Moscovium is a synthetic and highly radioactive chemical element with the symbol Mc. It has the atomic number 115 on the periodic table. Scientists classify this rare material as a superheavy transactinide element. It exists only for a tiny fraction of a second before breaking apart completely.
In more detail
Moscovium sits in group 15 and period 7 of the modern periodic table. This specific placement puts it right below the metal bismuth in the nitrogen group. Lighter elements in this specific group usually prefer a +5 oxidation state.
An oxidation state describes how many electrons an atom loses, gains, or shares. Moscovium behaves differently due to a relativistic effect known as spin-orbit coupling. Fast-moving electrons alter their behavior and change the chemistry of the entire atom.
Because of this effect, moscovium likely favors a +1 or +3 oxidation state instead. Scientists have discovered a few specific isotopes of the element moscovium. An isotope is a version of an element with a specific number of neutrons.
The most stable version discovered so far is the isotope moscovium-290. It undergoes alpha decay and releases a particle made of protons and neutrons. This isotope has a very brief half-life of approximately 0.65 seconds.
A half-life measures the time required for half of a radioactive sample to decay. This incredibly short lifespan prevents the gathering of any visible amounts of the metal. Researchers must conduct all of their empirical studies on isolated and individual atoms.
We do not know the actual physical appearance or solid structure of this metal. Scientists must predict its bulk chemical properties using complex math instead of physical experiments.

Scientists generate moscovium in specialized laboratories to conduct advanced nuclear physics research. They achieve this by using a large machine called a particle accelerator. The machine shoots a powerful beam of calcium-48 ions at very high speeds. These accelerated ions crash directly into a target made of radioactive americium-243. This high-speed collision sometimes fuses the different atoms together to create moscovium.
Frequently asked questions
Why is moscovium so difficult to study?
Its most stable isotope decays in less than a single second. This rapid decay means the element disappears almost immediately after scientists create it.
Where does moscovium get its name?
The element is named after the Moscow region located in Russia. This name honors the Joint Institute for Nuclear Research located in the city of Dubna.
