Atomic number 115
Moscovium
Post-transition metal
No photo: here’s why
Moscovium is a synthetic element made only in vanishingly small, intensely radioactive amounts - its atoms decay so quickly that no piece big enough to see or photograph has ever existed.

How dangerous is it?
Named for the Moscow region where it was made, this element exists only as a few atoms in a lab before they quickly decay.
- RadioactiveImmediate
It is highly radioactive on paper, but its atoms last only an instant and never accumulate.
Made and measured remotely by a small number of research teams behind shielding.
How it bonds· family overview
Moscovium (Mc) is a synthetic super-heavy p-block element. Group trends predict post-transition-metal behavior (a small set of low oxidation states, soft metallic character), but only a handful of atoms have ever existed.
