There is a classification of minerals known as elemental minerals, that meet all the requirements of the definition of a mineral: solid, naturally occurring, crystalline structure, definite chemical formula, and inorganic. Elemental minerals include gold, silver, copper.
Oxygen
Some elements occur in nature in a pure form, and not as part of a compound with other elements. Elements such as copper, silver, and gold are also minerals. Almost all pure, solid elements are mentals.
Yes, elements and compounds can exist separately.
All elements and all compounds do not exist as molecules. As examples, noble gases exist as individulal atoms and ionic compounds form lattices.
"Atoms" of the compound iron oxide do not exist, but the compound contains iron and oxygen atoms, both in the form of ions.
"Atoms" of the compound iron oxide do not exist, but the compound contains iron and oxygen atoms, both in the form of ions.
"Atoms" of the compound iron oxide do not exist, but the compound contains iron and oxygen atoms, both in the form of ions.
Isotopes of elements exist. There are no isotopes for compounds and calcium chloride is a compound.
No, it is a compound. Compounds are made up of elements, and elements are made up of atoms.
Today are known 118 chemical elements; 98 are considered as natural elements (but some have also and an artificial origin).
Simply because they exist in their natural state. Most elements are naturally found in compounds (ores, minerals) and must be processed to access the actual elements.
Because the ionic bonds cause the molocules to stablize and become less volatile.
