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.
What else can I help you with?
Active elements that never exist alone in nature are known as what?
diatomic
Why milk is a mixture?
Milk is a mixture because it is a combination of water, fats, proteins, sugars, vitamins, and minerals. These components are not chemically bonded together, allowing them to exist in the liquid as separate entities.
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.
Why helium and magnesium are both elements and not compound?
Helium and magnesium are both elements because they consist of only one type of atom. In contrast, compounds are made up of two or more different elements chemically bonded together. Helium and magnesium exist in their pure forms as single atoms without being chemically combined with other elements.
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
Active elements that never exist alone in nature are known as what?
diatomic
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.
Why milk is a mixture?
Milk is a mixture because it is a combination of water, fats, proteins, sugars, vitamins, and minerals. These components are not chemically bonded together, allowing them to exist in the liquid as separate entities.
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.
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.
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.
Active elements that never exist alone in nature are known as?
Active elements that never exist alone in nature are known as reactive elements. These elements are highly reactive and readily form compounds with other elements to achieve a more stable state. Examples include sodium, potassium, and chlorine.
How would you define a mixture based on what you have observe?
A mixture is a combination of two or more substances that are not chemically bonded together and can be separated through physical means. The individual components retain their properties and can exist in varying proportions within the mixture.
Why a certain atom exist alone?
it can exist alone as a diatomic molecule eg O2 oxygen
What does compound exist of?
A compound is a substance made up of two or more different types of atoms that are chemically bonded together. These atoms can be from different elements or the same element. The properties of a compound are different from the properties of the individual elements that make it up.
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
