Document Summary
Mineral = any naturally occurring inorganic (no h 2 bonds in it) solid that possesses an orderly crystalline structure and can be represented by a chemical formula. Sio 4 (silicate) is a mineral and is not organic. Rock = an aggregate (mix) of minerals, but they can be other things (like limestone or coal or volcanic glass) *rocks can be organic, but minerals can"t silicon) that we commonly see near or on earth"s surface. 8 elements make up the majority (98%) of all rocks and minerals (46. 6% of oxygen, and 27. 7% of. Other minerals like silver, gold, etc that we mine for are only tiny amounts in the earth"s crust. Ionic bonds = electron transfer; the element has a much stronger affinity. Electrons are transferred, positive and negative attract have very strong bonds and tend to make elements hard in texture result in highly conductive and the ease with which metals bend.
