| Question | Answer |
|---|---|
| what is a mineral? | a naturally formed inorganic solid that has a definite crystaline structure |
| what is a silicate mineral? | a mineral that contains a combination of silicone, oxyegen and one or more metals |
| what is a example of a silicate mineral | Quartz |
| what is a nonsilicate mineral | a mineral that does not contain a compund of silicate and oxyegen |
| give 6 examples of nonsilicate minerals | native elements,oxides,carbonates,sulfates,halides,sulfides |
| what is a native element | one element,copper gold or silver. used in communication and eletronic equipment |
| what is a carbonate | mineral that contains carban and oxyegen in the chemical structure,used in cement builiding |
| what is a halide | compounds that are formed when flourine chlorine iodine or bromine combine wuth sodiumn potassimn or calcuim used in chemical industry and detergents |
| what is a oxide | compunds that form when a element such as aluminum or iron combines with oxygen used to make abrasives aircraft parts and paint |
| what is a sulfate | minerals that contain sulfur and oxygen used in toothpaste and cosmetics |
| what are sulfides | minerals that contain more than 1 elemny such as lead iron nickel combined with sulfur used in bateries and electronic parts |
| what is a elemnt | a substance that cannot be speprated or broken down into a substance any chemical means |
| what is a compund | substance made up of atoms of 2 or more different elements joined by a chemical bound |
| what is a crystal | a solid whose atoms ,ions, or molecules are arranged in definate patern |
| propetries to identify minerals | color,luster,streak,cleavage,and fracture hardness desnity and special properties |
| luster | way a mineral refelcts light |
| streak | color of the powder of mineral |
| cleavage | splitting of a mineral in smooth flat surfaces |
| fracture | breaks on uneven surfaces |
| hardness | measure of ablitiy to resit scratching |
| hardest mineral | diamond |
| density | ratio of mass of a substance to the vloume of the substance |
| special properties | flouricene,chemical reaction,magetism, taste, optical properties,radioactivity |
| flouricene | glow under ultra violent light |
| chemical reaction | become bubbly and fizz |
| optocal properties | cuases a doubled image |
| magentism | natural magnetsa that atract iron |
| taste | halite has a salty taste |
| radioactivity | contains raduim or uranuim can be dectecde by a gieger counter |
