You think probable to diamond, graphite, amorphous carbon, fullerene, graphene, etc.
Elements.
Some examples of pure substances include elements like gold, oxygen, and carbon as well as compounds like water (H2O), sodium chloride (NaCl), and glucose (C6H12O6). Pure substances are materials that are made up of a single type of atom or molecule.
CO2 is a pure substance made of two elements, Carbon and Oxygen.
All these compounds can be obtained as very pure substances.
The most pure basic substances are elements, which are made up of only one type of atom. Elements like gold, oxygen, and carbon are examples of pure basic substances. They cannot be broken down into simpler substances by chemical means.
Pure substances are made up of a single element, or a single compound. Table salt is a pure substance because it is made up of only the compound NaCl (sodium chloride). Diamond is a pure substance, it is made up of the element carbon. Air is not a pure substance, it is a mixture of several gaseous elements and compounds (nitrogen, oxygen, carbon dioxide..) Distilled water is a pure substance made up of a single compound H2O.
Carbon is an example of an element, which is a pure substance that cannot be broken down into simpler substances by chemical means.
Steel is not a pure element, as it is an alloy composed primarily of iron with small amounts of carbon and other elements.
yes, a diamond is a crystalline form of pure carbon, there for making it a pure substance.
All substances are MADE FROM elements but they are not elements. For example CH4 is made of one carbon atom and four Hydrogen atoms. Carbon and Hydrogen are pure elements but CH4 is not an element.
These are substances that contain only one type of atoms/molecules. For example, diamond is a pure substance. Diamonds are made of strictly carbon atoms. Melting points and Boiling points of pure substances always remain constant !
Diamond is not a solution in the typical sense. It is a crystalline form of carbon, not a homogeneous mixture of substances like a solution.
