Unit 3 Minerals E.S.

TermDefinition
Elements A substance that cannot be broken down into simpler substances by ordinary chemical means Examples: carbon (C) and Sodium (Na)
Bohr Model Energy level:1 2 3 4 5 6 # of Electrons: 2 8 18 32 50 72 Model where you place the amount of electrons in an element on the circles. What are the amounts of electrons that can be placed on each energy level?
Ore A rock that contains high enough concentrations of a desired substance, such as metal, so it can be mined for PROFIT.
Hardness How easily a mineral SCRATCHES materials.
Mineral Characteristics What are the following?: 1.)Naturally forming, 2.)Inorganic, 3.)Solid substance, 4.)Crystalline Structure, 5.)Specific chemical composition
Streak The COLOR of the powdered form of the mineral.
Fracture Minerals that break at RANDOM with rough or jagged edges.
Cleavage Mineral break along SMOOTH, flat surfaces and every fragment has the same general shape.
Color Visible color of the mineral.
Gemstone What are 2 characteristics that make gemstones, gemstones? A rare and attractive mineral that can be worn as jewelry. Useful and Valuable
Minerals A naturally occurring, inorganic solid, with a crystal shape that repeats itself, and a definite chemical composition (elements always the same.)
Density Weight of mineral compared to the weight of equal volume of water. (Mass over Volume or M over V)
Solid All minerals are ______. AND A ______ matter with tightly packed atoms or ions that has a definite shape and volume.
Luster Surface REFLECTION.
Metallic Luster Shiny like metal.
Nonmetallic Luster Dull, non-shiny surface.
Native Element Mineral made of only one type of element Ex. Sulfur
Iron The abundant metallic mineral resources used everyday.
Crystalline Form Minerals are made up of more crystals. The internal arrangement of atoms determines the shape of the crystal. This geometric pattern is reflected by the shape of the mineral.
Bauxite Aluminum is mined from rocks that have been exposed to weathering in a tropical environment Ex.: ________.
Silicates Largest mineral group.
Silicates Contain oxygen and silicon. Most abundant group of minerals. Ex. Quartz, Feldspar, Mica
Non-Silicates Makes up 5% of the crust includes some of the most important minerals. Does not contain silicon. Ex. Iron, Copper, Gold, Calcite, Halite
Quartz SiO2 Most common mineral in Earth's crust is _______.
Know How To: Identify minerals on Moh's hardness scale. Know How To: Identify minerals on Moh's hardness scale.
Know the chemical symbol for Oxygen and Silicon. Oxygen: O, Silicon: Si
Ore:A rock that contains high enough concentrations of a desired substance, such as metal, so it can be mined for PROFIT. Gemstone:A rare and attractive mineral that can be worn as jewelry. Metals: Mostly abundant Metallic minerals. Precious Metals: Rare. Understand the difference between ore, gemstones, metals, and precious metals.
If it contains high enough concentrations of a desired substance, such as metal, it can be mined for profit. Understand how profitability applies to ore.
Know how to use a physical properties chart to label characteristics. Know how to use a physical properties chart to label characteristics.
Use Mass divided by Volume. Know how to find the density of a mineral.
Know how to calculate density by using D=m/v. Know how to calculate density by using D=m/v.
Know how to read a graduated cylinder to determine volume by displacement. Know how to read a graduated cylinder to determine volume by displacement.
Know how to identify a correct Bohr model for an atom of a particular element. Know how to identify a correct Bohr model for an atom of a particular element.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
