This type of element is usually dull, brittle, and not a good conductor.
What is a nonmetal?
_______________ is the ability of one mineral to scratch another mineral; or the ability to RESIST being scratched.
What is hardness?
Mrs. Morris used a hammer to test this property of minerals. She observed that some minerals broke into flat pieces.

What are SAFETY GOGGLES? -protect your eyes!
These pieces of equipment are needed to conduct an investigation over mass and volume.
A. graduated cylinder, spring scale B. graduated cylinder, triple beam balance C. beaker, spring scale
What are graduated cylinder (VOLUME) and triple beam balance (MASS)?
_____________ means a substance can be stretched into a wire without breaking.
What is ductile or ductility?
You are examining an object in class. It is pale yellow, brittle, solids, and is not very shiny. This sample is most likely a _________________ A. nonmetal B. metal C. metalloid D. semi-conductor
What is (A.) nonmetal (brittle, dull)??
This mineral cannot be scratched by Feldspar but can be scratched by Topaz
What is Quartz?
The number above a chemical symbol on the periodic table, that ascends from left to right on the table.
What is atomic number?
The density of this substance is 1.0 g/ml. If another substance has a density >1.0g/ml it will sink, and if it is <1.0g/ml it will stay above it (float).
What is water?
Luster, ductility, conductivity and ________ describe METALS.
What is Malleability?
You are testing samples of metals, nonmetals, and metalloids. You use a battery, wire, and a bulb to see if the samples will complete the circuit to cause the bulb to light up. Then, you use a bright light on each sample. The tests are to determine the properties of: A. streak and hardness B. luster and conductivity C. color and conductivity D. hardness and luster
What are (B.) luster/shine with light and conductivity (transferring energy or heat)?
Beyonce has tested these properties of the rare mineral that she has. It looks glass like, is a 10 on Mohs Scale, and does not break in flat surfaces.
What are Luster, Hardness, and Cleavage?
How a mineral or metal appears when it reflects light is known as __________________.
Luster
You find a strange shaped, heavy rock. You want to find the density, so you can determine what it is. It's mass is 48.6 grams. To find the volume you place it in graduated cylinder that had 10 ml. When you placed the rock in the water it went up to 16 mL. Find the density.
8.1 g/mL
You need to find the density of your house key. The volume of the key is 5 mL, and the mass is 39.5 g. Aluminum has a density 2.70g/mL Steel has a density of 7.90 g/mL Copper has a density of 8.90 g/mL. The key is made out of
What is STEEL, 7.90 g/mL?
These elements are on the staircase of the Period Table. They are sometimes referred to as semiconductors because they are not good conductors but may still have the ability to conduct energy.
What are metalloids?
These rare and very hard minerals may be found in different colors, shapes and sizes.
What are gemstones?
When writing these you must use a capital letter if it is a single letter or a capital and a lowercase letter if it has two letters, ex: "O" "Na"
What are Chemical Symbols.
