Osmium is a chemical element that has the symbol Os and atomic number 76. So it is made of itself.
Individual atoms are, as usual made up of protons, neutrons and electrons. The protons and neutrons are made up of quarks.
That aside, see the first paragraph in this answer.

What is the name of the following compound OsO4?
Osmium tetroxide
Can you make jewelry out of osmium?
Yes, but its probably not a good idea. "Osmium reacts with oxygen at room temperature forming volatile osmium tetroxide. Osmium tetroxide is highly volatile and penetrates skin readily, and is very toxic by inhalation, ingestion, and skin contact."
How reactive is osmium?
Osmium has varying states of reactivity. Its pure state tends be quite reactive and is rarely used unless alloyed. Osmium tetroxide is extremely reactive, whereas osmium dioxide has very little reactivity.
What are the cross-linking fixatives?
Cross-linking fixatives are types of fixatives that are used to quickly halt enzymatic degradation. Formaldehyde, osmium tetroxide, and glutaraldehyde are the most commonly used cross-linking fixatives.
Why is a ballpoint made of an alloy?
Osmium
What is the name of the following compound OsO4?
Osmium tetroxide
What is the chemical formula Osmium tetroxide?
It is OsO4
How did osmium get its name?
From Greek osmē, smell (from the strong odor of osmium tetroxide).Named osmium after http://www.answers.com/topic/greek-language osme meaning "a smell", because of the smell of the volatile osmium tetroxide

What is the formula for OsO4?
Osmium tetroxide is the chemical compound with the formula OsO4.
Is osmium malleable?
Yes, osmium is capable of being reactive. It can easily create a volatile tetroxide reaction at room temperature with oxygen.
What does Osmium tetroxide look like?
It is colourless but most of its samples appear yellowish.
How reactive is osmium?
Osmium has varying states of reactivity. Its pure state tends be quite reactive and is rarely used unless alloyed. Osmium tetroxide is extremely reactive, whereas osmium dioxide has very little reactivity.
What does Osmium smell like?
Osmium itself has no smell. The "smell" (the name "osmium" comes from the Greek for "smell") is from the volatile osmium tetroxide, and while it may be futile to attempt to describe a smell, it's generally said to be an acrid scent similar to that of chlorine.
What is the main purpose of periodic acid?
Not sure if it's the main use, but the most common use I have come across is the reaction with osmium tetroxide, where periodic acid is used to cleave the bond between a 1-2 dihydroxy- compound, which is generated bye the reaction between an alkene and osmium tetroxide
Give an example of osmium?
Osmium is a naturally occurring chemical element with the symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal. An example of osmium is osmium tetroxide (OsO4), which is a highly toxic and volatile compound used in various chemical reactions, particularly in organic synthesis and staining biological samples for electron microscopy.
What types of dyes are used for negative staining?
acidic dyes such as eosin, acid fuchsin, and nigrosin
