Minerals must have all five of these traits. They are; is a solid, formed in an inorganic process, has a crystalline shape, naturally occurring, and a chemical composition. A solid is self explanatory, not a liquid or a gas. Naturally occurring is when are found in nature and not man made. Being inorganic means the item is and never was alive, so not people, trees, plants, and animals. A fixed composition has a formula like AU(gold) and has two or more elements. Last but certainly not least is a crystalline shape which is like it sounds it has a definite shape that the have atoms arranged. Almost every single mineral is a compound, but not all.
