100
A negatively charged, subatomic particle.
What is an electron?
100
The formula for a regular shaped object would be length X width X height.
What is volume?
100
This state of matter has no definite shape but does have a definite volume.
What is a liquid?
100
An example would be "The magnet is black".
What is a physical property?
100
You must observe this to observe a chemical property.
What is chemical change?
200
Scientists often use these types of calculations to determine what kind of substance they are dealing with.
What is density?
200
All matter is composed of these.
What are atoms?
200
The changes in state between solids and liquids.
What is melting and freezing?
200
When matter changes from one form to another without a change in chemical properties.
What is a physical change?
200
This characteristic can be observed without changing the substance.
What is a physical property?
300
This subatomic particle adds nothing to the charge of an atom.
What is a neutron?
300
The measurement of how much matter is in an object.
What is mass?
300
This substance sublimates into a purple gas.
What is solid Iodine?

400
This chemical property describes a substances ability to ignite.
What is flammability?
400
A property of matter that describes its ability to change into a new substance.
What is chemical property?
500
This value is obtained by adding the number of protons plus neutrons for a given atom.
