Lattice atoms are held in place by atomic bonds. Bond characteristics govern mineral properties: covalent- molecules are held together through sharing electrons, metallic- nuclei and inner shells float in a sea of free electrons, electrons stream through metal. Ionic- give up electrons, both filled outer shells if there is an electric current: van der whaals and hydrogen help hold molecules together. Polymorphs- same composition but different crystal structure, diamond and graphite are carbon polymorphs. Color- diagnostic for few minerals, varieties reflect trace impurities. Hardness- scratching resistance of mineral, compared to mohs scale. Luster- the way a mineral scatters light, metallic or nonmetallic. Streak- the color of mineral crushed on a ceramic plate.
