what can the cost of this element range from?
$400 per troy ounce
Osmium
While the price of $400 per troy ounce has remained steady since the 1990s, inflation since that time has led to the metal losing about one-third of its value in the two decades prior to 2019.
the density of osmium which is the densest metal It is approximately twice as dense as lead and slightly denser than iridium. what is osmium? It is a chemical element with the symbol Os and atomic number 76. where did it get its name from? From Greek word  "osme" meaning "smell". who was the first one to discover numbers for atoms? Henry Moseley are there elements that are also missing? There were seven elements  which were not found and therefore identified as still undiscovered, but from 1918 to 1947, all seven of these missing elements were discovered what is the colour of the former chemical element? Bluish-white transition metal what does it react when it comes in contact with other elements? Osmium tetroxide  is formed when powdered osmium is exposed to air,  it  forms red osmates upon reaction with a base, with ammonia, it forms the nitrido-osmates, etc. can you state one physical property of the first element you mentioned? UNANSWERABLE does the former element also have isotopes? Yes, it  has seven naturally occurring isotopes, six of which are stable and undergoes alpha decay name you name some of its naturally occurring isotopes? UNANSWERABLE does this element have any uses? Osmium alloys such as osmiridium are very hard and, along with other platinum-group metals, are used in the tips of fountain pens, instrument pivots, and electrical contacts, as they can resist wear from frequent operation. Osmium tetroxide has been used in fingerprint detection and in staining fatty tissue for optical and electron microscopy. do we need to take any care while handling this element? Yes, it is highly volatile and penetrates skin readily, and is very toxic by inhalation, ingestion, and skin contact.

Osmium [SEP] Price
Osmium is usually sold as a minimum 99.9% pure powder. Like other precious metals, it is measured by troy weight and by grams. The market price of osmium has not changed in decades, primarily because little change has occurred in supply and demand. In addition to so little of it being available, osmium is difficult to work with, has few uses, and is a challenge to store safely because of the toxic compound it produces when it oxidizes. While the price of $400 per troy ounce has remained steady since the 1990s, inflation since that time has led to the metal losing about one-third of its value in the two decades prior to 2019.
