Document Summary
Minerals are made of one or more elements. Elements are composed of one or more atoms: identify the most common elements and minerals. In the same mineral structure, ions of similar charge and size can be substituted/interchanged for eachother. Example: olivine has a compositional range of fe2sio4 to mg2sio4. Minerals with the same chemical composition but different crystal structures. A polymorphism is usually more stable than the other one at a certain condition. Diamond vs graphite: identify mineral specimens in the rock and mineral kit, what are the names of common gemstones identify the mineral name for each. Minerals form from compound bonding (ionic, covalent, metallic) Strongest bonding, from by a positive and negative compound bonding. The election of one compound is stolen by another compound. Minerals formed by more abundant elements are more common (ex. Minerals are identified by its chemical composition and crystal structure.
