Metals
The way a metal’s surface reflects light is called
What is Luster
Nonmetals are usually found on what side of the Periodic table?
What is the right side.
Where are metalloids typically located on the periodic table
Along the stair case/between metals or nonmetals
Name 3 physical properties of a Physical change
Color, Smell, Density, boiling point, melting point, freezing point
What is a Homogeneous mixture
all parts of the mixture have the SAME properties and cannot be visually distinguished from one another.
refers to the way most metals can be stretched into wires.
What is Ductile?
List 3 physical properties of a nonmetal.
Brittle, dull, insulator, lacks luster (not shiny), low density
Which of these elements is a metalloid: oxygen, carbon, silicon, or sodium
Silicon
What is the definition of a physical property
Any characteristic of a substance that can be observed without changing the substance.
What is a heterogeneous mixture?
a mixture made of two or more substances that are combined (mixed) together but not dissolved together
How many elements on the periodic table that are classified as metals.
What is 88?
A tendency to break rather than flex or bend
Brittle
Explain why a metalloid might be considered "semi-conductor" of electricity
Because it can conduct electricity under certain conditions, but not as well as a typical metal
Mixing salt and pepper, is this a chemical or physical property? Why?
Physical property because no new substance is formed through a chemical reaction. It did not catch fire, it did not combust.
List 3 examples of a Homogeneous mixture
Tea
Milk
Smoothie
air
Metals are found on the what side of the periodic table.
What is the Left?
A material that does not conduct heat or electrical current.
Insulator
Name one physical property that might be similar between a metalloid and a metal.
What is Luster (shiny)
List 3 examples of a chemical change
Rusting of iron
combustion (burning
Cooking an egg
Milk becomes sour
Toasting bread or marshmallow
List 3 examples of a heterogeneous mixture
Salad
Pizza
Mixed nuts
Mixed candy
Sand and rock
Give me THREE Physical Properties that describe metals.
What is Ductile, malleable, conductor, density, Luster etc. ?
Describe the physical properties of sulfur
pale yellow, brittle, odorless solid at room temperature, with a low melting point, poor conductor of electricity, and is insoluble in water;
what is unique about Metalloids?
Metalloids shares the same properties of Metals and nonmetals

b. Taking a glass of water and freezing it by placing it in the freezer.
c. A plant collecting sunlight and turning it into food. d. Your dog ripping up your homework.
