Which of the following is a property of a nonmetal?
can be hammered into thin sheets
conducts electricity and heats well
is brittle and breaks easily
has a shiny, metallic luster
The majority of the periodic table is made up of
Metals
Nonmetals
Metalloids
Noble gases
The word “luster” refers to which property of matter?
The ability to conduct electrical or thermal energy
Capable of being drawn out into thin wires
The way a surface appears when it reflects light
Suitable for being shaped by beating or rolling
All of the following are properties used to classify elements as metals, nonmetals and metalloids EXCEPT--
Luster
Texture
Conductivity
Malleability
All of these properties describe metals except--
Malleable
Brittle
Conductor
Shiny
Conductivity is a physical property of matter that describes its ability to-
transfer thermal and electrical energy
exist in nature as a solid, liquid or gas
be hammered and rolled into thin sheets
reflect light from its lustrous surface
Unlike nonmetals, most metals tend to--
conduct electricity and heat well
break easily when hammered
be gases at room temperature
have less luster and shine
Which elements are to the LEFT of the zigzag?
metals
nonmetals
metalloids
Electrical wires are made from metals such as copper and chromium because-
wires can be stretched and bent
most metals have a metallic luster
electricity flows in a complete circuit
metals are good conductors of electricity
Which of the following is the correct calculations for determining the density of an object with a mass of 325g and a volume of 5mL?
5 ÷ 325
5 X 325
325 ÷ 5
5 + 325
What is density?
the amount of matter in an object
anything that has mass and volume
the amount of space an object takes up
the mass of a material in a given volume
Why do some objects float in water?
they are more dense than water
they are less dense than water
they are lighter than water
they are heavier than water
An object has a mass of 441g and volume of 10cm3 . WHat is the density of the object
34.1
44.1
40.2
34.8
What is the density of an object with a mass of 25g and volume of 37 centimeters?
.68
.54

.81
A student measured the mass and volume of a metal sample using a triple beam balance and a graduated cylinder. The sample has a mass of 7 grams and a volume of 4 cm3.
What is the density of the metal sample rounded to the nearest tenth?
1.8 g/cm3
.175 g/cm3
.3 g/ cm3
12.4 g/cm3
Determine the density of a sample of unknown substance with a mass of 6 g and a volume of 12 cm3.
0.5 g/cm3
1 g/cm3
5 g/cm3

Physical properties of minerals such as color, luster, hardness and streak are used to determine what about a mineral?
Identity
Mass
Age
Location
How are minerals identified using luster?
Minerals are scratched against each other. The mineral that does the scratching has the most luster.
Using a balance, the mass is recorded. Which mineral has the largest mass has the most luster.
They are rubbed together on unglazed tile. The powder left behind is luster.
The way the light reflects off a mineral determines the luster of the mineral.
When determining which mineral will scratch other minerals, you would need to refer the:
Periodic Table of Elements
Rock Guide Book
Mohs Hardness Scale
Richter Scale
Use Moh's hardness scale to answer the question. Which of the following is a correct statement about a a mineral with a hardness rating of 7?
The mineral can scratch Apatite and every mineral with a hardness scale number lower than 7.
The mineral cannot be scratched by Apatite, but can be scratched by Feldspar.
The mineral can scratch Calcite, but cannot scratch Apatite.
The mineral can scratch Apatite and every mineral with a hardness scale number higher than 7.
Which of the following in NOT true of all minerals?
definite chemical composition
definite crystalline shape
made in laboratories
solids
Which of the following is NOT a way that minerals are able to be classified?
Streak
Hardness
Luster
State of matter
Which element most likely has a shiny luster?
cobalt
arsenic
hydrogen
carbon

Mass is
a measure of space
a measure of amount of matter
a metric unit of volume
a comparison of density between materials
Volume is
a measure of space that matter occupies
a measure of amount of matter
the basic metric unit of mass
a comparison of density between objects
Displacement is
a procedure to measure the volume of a solid by placing it in a known amount of liquid.
the mass of a substance divided by its volume.
a metric unit of volume.
a measure of the space that matter occupies.
