Yes they will both react with fluorine and oxygen to form compounds. OsO4 is particularly useful even though toxic
osmium and iridium
osmium and iridium
Either osmium or iridium. It's a pretty close call. Theoretically iridium should be more dense; actual measurements indicate that osmium is very slightly denser.
Either osmium or iridium. The densities are very close.
These metals are three: ruthenium, iridium, osmium.
iridium osmium platinum plutonium
The element used to harden pen points is commonly iridium. Iridium is a dense and corrosion-resistant metal that is often alloyed with other metals to create durable pen nibs that retain their shape and provide a smooth writing experience.
Osmium tetroxide
Osmium and iridium are the two elements with highest density.
The chemical compound name for OsCl4 is Osmium tetrachloride.
Langford Todd Bourland has written: 'The magnetic susceptibilities of osmium, iridium and platinum' -- subject(s): Iridium, Magnetism, Osmium, Platinum
Osmium is slightly denser than Iridium. Osmium has a density of around 22.59 g/cm3, while Iridium has a density of approximately 22.56 g/cm3. Both elements are among the densest naturally occurring elements.
