What makes a mineral? / 5 characteristics of a mineral.
Crystalline, Homogeneous, Inorganic, Solid and Natural Occuring.
• It’s compound definable chemical composition. • A type of mixture where all the substances cannot be distinguish or pointed out w/o, separating of mixture. • uniform composition.
Homogeneous Compound
Atoms vibrate in place in fixed pattern.
Crystalline Solid
Atoms vibrate in place in more random arrangements.
Amphorphous
Contain an orderly arrangement of atoms. The geometry of the arrangement defines the crystal lattice.
Crystalline Solid
• Irregular pattern of ions, molecules or atoms in a solid. • Melt over a range of a temperature • No definite heat fusion
Amphorphous
• Regular and repeating arrangement of components in a solid. • Have a sharp melting point. • Definite heat fusion.
