Metals
Where do metals appear on the periodic table?
Metals appear to the left of the dark zig-zag line on the periodic table.
Where are the non-metals located on the periodic table?
Where can metalloids be found on the periodic table?
Metalloids can be found around the dark zig zag line that separates metals and nonmetals.
What is density?
Density is defined as mass per unit volume. It is a measure of how tightly packed and how heavy the molecules are in an object. Density is the amount of matter within a certain volume.
Name three properties of metals.
Metals have luster. This means they are shiny.
Metals are ductile. This means they can be drawn into wire.
Metals are malleable. This means they can be hammered into sheets.
Do non-metals have luster?
Non-metals do not have luster, they are dull.
What are metalloids properties similar to?
Metalloids have properties of both metals and nonmetals.
What is proof that ice and water have different densities.
The fact that the ice floats in the water means that the water has a higher density than the ice.
Name three different properties of metals.
Metals have a high melting point. They are also very dense.
Metals are good conductors for electricity and heat.
A chemical property of metal is its with water and oxygen. This results in corrosion and rust.
Nonmetals are brittle, so they break easily. THis means nonmetals are not ductile or malleable.
Do metalloids have luster?
How to find density?
Find the mass of the object. Find the volume of the object. Divide density= mass/volume.
Name four examples of metals.
Nickel, Rubidium, Gold, Copper.
Do nonmetals have high or low density?
Nonmetals have low density.
How well do they conduct electricity and heat?
They conduct electricity and heat better than nonmetals, but not as good as metals.
Name other formulas with density, mass, and volume.
M=DxV
D=M/V
V=M/D
⭐Bonus- Why is hydrogen with the metals instead of the non-metals?
It has only one valence electron, and so does the rest of the row it's in.
How high or low is a nonmetals melting point? What does this cause?
Nonmetals have a low melting point. This causes them to be poor conductors of heat and electricity.
Are metalloids malleable or ductile?
Metalloids are malleable and ductile.
What has a greater density, feathers or rocks?
Feathers.
