Term | Definition |
Elements | An element is a substance that cannot be broken down into simpler substances by ordinary chemical means. |
Bohr Model | 1st energy level is two, cannot go above 8 |
Ore | Is a rock that contains high enough concentrarions of a desired substance, such as metal, so it can be mined for a profit. |
Hardness | How easily a mineral scratches materials. |
Mineral Charaistics | Color, crystal shape, clevage/fracture, luster, hardness, streak, specific gravity. |
Streak | The color of the powdered form of the mineral. |
Fracture | Minerals that break at random with rough or jagged edges. |
Cleavage | Minerals break along smooth, flat surfaces and every fragment has the same general shape. |
Color | Visible color of the mineral. (Least reliable test.) |
Gemstone | A gemstone is a rare and attractive mineral tha can be worn such as jewlery. |
Minerals | A mineral is a naturally occuring, inorganic solid, with a crystal shape that repeatrs itself, and a definite chemical composition (elements always the same.) |
Density | A specific gravity, attraction to gravity, bending of light, smell and taste. Formula for density: mass/volume. |
Solid | All minerals are solids. A solid matter with tightly packed atoms or irons that has a definite shape and volume. |
Luster | Surface reflection |
Metallic Luster | Shiny like metal |
Nonmetallic luster | Dull, non-shiny surface. |
Native Element | a mineral made up of only one element and uses its ame such as iron. |
Iron | (Fe) it is the main element in steel, which is used in buildinigs and vehicles. |
Crystaline form | Particles that dissolve in a liquid, Melted materials solidify and form crystals. |
Bauxite | The most abundant metallic mineral resources. |
Silicate | (Si) must have silicon and oxygen. |
Non Silicate | Dose not have silicon and oxygen. |
