| None of meitnerium's chemistry has been researched, but it should resemble other elements of group 9, like iridium. |
| It is also classified with a group of similar metals, including ruthenium, rhodium, palladium, osmium, and iridium, with similar properties. |
| During cupellation, osmium and ruthenium are partly volatilised and iridium is partly absorbed by the cupel. |
| Along with ruthenium, rhodium, osmium, iridium, and platinum, it belongs to the platinum group of metals. |
| These so-called face-centered cubic close-packed structures are common in metals such as aluminum, rhodium, iridium, copper, silver, and gold. |
| The earth's crust is depleted in iridium and other platinum group elements, while meteorites are enriched in them. |
