Document Summary
Why polymorphs (diamond and graphite) have such different physical properties. Explan the structure and importance of silicate materias. Minerals can be put into families, such as silicates. Minerals relate to chemistry: must understand the chemical level. Bonding, elements, and what is causing the structure. Minerals naturally occurring, inorganic crystalline solid material with a specific chemical composition and internal structure. Look at the internal earth, whole earth, and earth"s crust. Whole earth: iron 35%, oxygen 30%, silicon 15%, magnesium 13% Earth"s crust: oxygen 46%, silicon 28%,aluminum 8%, iron 6% Silicon nonmetallic element with atomic number #14, chemical symbol si. Oxxurs extensively in the crust in silica and silicates. Silicates any mineral that contains the elements silicon and oxygen bonded together as the sio4 molecule, typically with additional materials. Inorganic not created from any organic substances. No, coal is made out of plants which have compacted to create a mineral.
