Iridium is normally found in naturally-occurring alloys, which makes the answer not quite either of those things. Iridium in its elemental metallic state is fairly inert chemically, so it's not completely ludicrous that a "nugget" of iridium might be found ... if there weren't so very little of it (it's one of the rarest elements in Earth's crust), so that it's much more likely to be found alloyed with copper or platinum.

Is the far few materials are elements than are not elements?
Very few elements exist in their free state in nature. The vast majority of them exist as compounds, chemically bonded to other elements.
What is made of two or more substances chemically bonded together?
Many compounds of three or more nonmetals exist. Examples include phosphoric acid and chloroform. Additionally, the very unstable compound carbonic acid is of this type.
What does technetium 99m exist as?
Technetium-99m can be bonded for medical uses with sestamibi, exametazime etc.
What kind of metal that can't dissolve by aqua regia?
There exist very few metals which remain unaffected by Aqua regia, two of which are Iridium and Rhodium
Why do noble gases exist independently in nature?
Noble gases have completely filled orbitals. They are stable, chemically inert, do not generally form compounds and hence exist as isolated atoms.
Active elements that never exist alone in nature are known as?
chemically reactive

What are mixtures and solutions?
Two or more subastances forms a mixture if they are not chemically bonded; a solution is a liquid homogeneous mixture (also exist solid solutions).
Does a single molecule have two atoms?
It depends whether it can exist alone or has a pair. Some atoms have semi-filled outer shells of electrons (sub-atomic particles) and therefore need to be covalently bonded with another molecule in order to be stable. Others can exist alone.
Do any compounds exist only as an atom?
No, a single atom would have to belong to a particular element. A compound must contain two or more different types of atom that are chemically bonded (either covalently or ionically) together.
Why does quartz abundantly exist in most soils rather than feldspar?
It is because quartz are consist of non-permeable substance than of the feldspar that is can easily break down to pieces because of lack of strong chemically bonded components.. > AGRI
What chemical elements have a subscript of two?
All the gases except the Noble(Inert) gases, which are monatomic.
Why a certain atom exist alone?
it can exist alone as a diatomic molecule eg O2 oxygen

What type of solids that can not be separated?
Chemically or physically. Chemically, elements can not be broken down. Chemically, a mixture of solids can be seperated in most cases through solubility, precipitation, and by using chemicals.
