: It is created in a particle accelerator by bombarding targets of heavy elements, such as americium-243, with ions of calcium-48.

: Moscovium is highly unstable; its most stable isotope, moscovium-290, has a half-life of only about 0.65 seconds. Researchers at Study.com note it is expected to be a solid at room temperature with a density of roughly 13,000
