Compound Atom Element What is the AN ELEMENT? The state of Mercury (Hg) at room temperature? Solid Liquid Gas What is LIQUID? A chemical symbol (H) is a shorthand way of writing the name of this. Molecule Compound Element What is AN ELEMENT? A substance made up of two or more elements chemically combined (H O). 2 Molecule Compound Element What is a COMPOUND? A shorthand way to write a compound, H2O is an example of one. Molecule Chemical formula Element What is CHEMICAL FORMULA? A natural solid formed from elements and compounds in Earth’s crust Dirt Minerals Rocks What is A MINERAL? All minerals are this state of matter Solid Liquid Gas What is SOLID? Mica splits into pieces that are… Cubes Sheets Hexagons What is THIN SHEETS? The splitting of a mineral into pieces with smooth, flat surfaces Cleavage Fracture Cracked What is CLEAVAGE? The breaking of a mineral into pieces with uneven surfaces Cleavage Fracture Cracked What is FRACTURE? The result of magma cooling underground Evaporation Precipitation Crystallization What is CRYSTALLIZATION? Ores are mined because they contain Crystals Useful metals & nonmetals Magnets What are USEFUL METALS AND NONMETALS? Two examples of precious stones are Feldspar and halite Ruby and hematite Sapphire and emerald What are SAPPHIRE AND EMERALD? When lava cools quickly, it forms this size crystal Large Coarse Small What is SMALL? This is the softest mineral listed on Mohs’ scale Diamond Talc Calcite What is TALC? The color of the powder left by a mineral Scratch Streak Acid test What is STREAK? The luster of a mineral that shines like a new coin Non metallic Metallic Transparent What is METALLIC? Magnetite is magnetic because it contains this Sulfur Iron Gold What is IRON? The formula for density D= v/m V=m*d D= m÷v What is D=M÷V? The acid test is used to determine if a mineral contains Gold Calcium carbonate Iron What is CALCIUM CARBONATE? The way a mineral reflects light Color Streak Luster What is Luster? Acid causes a mineral containing calcium carbonate to do this Nothing Fizz Burn What is FIZZ? Fluorite = 4 and Quartz = 7 Can fluorite scratch quartz? Yes No Yes, if you press hard enough What is NO? The hardest mineral on Mohs’ scale Talc Diamond Gold What is DIAMOND? Mineral Hardness Talc 1 Gypsum 2 Calcite 3 Fluorite 4 Apatite 5 Feldspar 6 Quartz 7 Topaz 8 Corundum 9 Diamond 10 Which minerals can NOT be scratched by feldspar? What is Quartz, Topaz, Corundum and Diamond?
