Anything that takes up space and has mass is called this.
What is matter?
This animal is arguably a liquid.
What is a cat?
Scientist use these to represent things that are too small for the human eye to see.
What is a model?
Two or more atoms joined together by a chemical bond.
What is a molecule?
Iron, Gold, Helium and Mercury are all examples of this.
What is an element?
The basic unit of matter is called this.
What is an atom?
My particles are packed together in a fixed arrangement.
What is a solid?
This model uses spheres to represent atoms and are shown by overlapping.
What is the space-filling model?
A substance that is made up of only one type of molecule, atom, or other unit of matter. (A scoop of this term would have the same properties as any other scoop)
What is a pure substance?
H2O (water), CO2 (carbon dioxide), and Deoxyribonucleic acid (DNA) are examples of this.
What is a molecule?
A substance made up of only one type of atom is called this.
What is an element?
My particles move and slide past each other and fill the shape of my container.
What is a liquid?
This model uses spheres to represent atoms and bars to represent the chemical bond.
What is a ball-and-stick model?

What is a mixture?
Acetaminophen and Quartz(sand) are examples of this.
An observable characteristic of a substance, such as color, density, or melting point is called this.
What is property?
My particles are far apart with no regular arrangement.
What is a gas?
This model uses one/two letter abbreviations to represent atoms and bonds.

What is a gas?
This property describes the amount of mass packed into a given volume.
What is density?
A sample of water changes from a liquid into water vapor. According to the particle model, what happens to the particles?
What is the particles move father apart and have no fixed arrangement.
Both crystals and a polymer are examples of this.
What is an extended structure?
Iodine atoms have more mass than iron atoms, yet solid iodine is less dense than solid iron. How is this possible?
The only example of the solid state of matter being less dense than its liquid state.
