crystalline, inorganic, and has a definite chemical composition. Minerals are typically formed through geological processes and have unique physical and chemical properties that distinguish them from other substances.
No. They can have radically different properties from the elements they're formed from.Easy example: Sodium chloride. Sodium is a highly reactive nonmetal. Chlorine is a highly reactive nonmetal. They combine into a very nonreactive compound - table salt.
Scientists classify rocks based on their mineral composition, texture, and how they were formed. These classifications help geologists understand the history and properties of rocks. There are three main categories for classifying rocks: igneous, sedimentary, and metamorphic.
In a chemical change chemical properties often change (like a substance's melting point or it's reactivity). In a physical change the materials have the same properties (a physical change would be like crushing rocks into sand). You can take wood, grind it into saw dust, but it is still wood. But if you burn it, the wood goes through a chemical change with the oxygen in the air and most of it is broken down into a gas (smoke) and the solid of which is left behind has a very different flammability property. (Suit, it doesn't burn.)

A substance that is formed from one type of atoms with a characteristic set of physical and chemical properties is called an element.

Physical.
Chemical reaction.
A compound that has the same properties as the elements that formed it is called a pure substance. Each element retains its chemical properties within the compound, but the compound itself may have different physical and chemical properties compared to its individual elements.
The chemical and physical properties of a compound are different than those of the elements from which it is formed.

New substances formed in a chemical reaction are called products. These products have different chemical properties than the reactants that were originally present, and the reaction is often characterized by changes in physical properties such as color, temperature, or state.
