Iridium is a member of the Platinum group of metals, and is one of the rarest elements in the Earths crust. There should have been more, but it dissolves in iron, so most if it will lie in the Earths core.
As a metal it has a remarkable set of properties - towards the top of most property lists. You should explore these for yourself.
[A remarkable piece of work by the Alvarez's discovered an Iridium anomaly in the world's crustal rocks, and this was eventually traced to a meteoric impact about 65 million years ago, and the cause of a mass extinction of many of the genera and species of that time. [Dinosaurs the spectacular example].
This meteorite impacted near Chixculub in the Yucatan peninsula of Mexico, and the meteor would have been about 10km diameter.]
Iridium, Einsteinium
Iridium is a metal element. Atomic number of it is 77.
Lead has a higher atomic number than iridium, which means a lead atom is heavier than an iridium atom. however iridium is denser, therefore if you had a block of iridium and a block of lead,the iridium block would be heavier
Iridium is a metal that is not safe to taste due to its toxicity. It has no discernible taste, as it is not meant to be consumed.
The formula for iridium(III) oxide is Ir2O3. It consists of two iridium atoms bonded to three oxygen atoms.
