Air is this type of substance.
What is a homogeneous mixture.
100
These are the three subatomic particles that make up an atom.

When solid water becomes liquid water it is this kind of change.
What is a physical change?
100
The rows in the periodic table.
What is a period?
200
It's the state of matter where molecules move freely past each other.
What is a liquid.
200
Water is this type of substance.
What is a compound?
200
These are the particles that are responsible for more than 99% of an atom's mass.
What are protons and neutrons?
200
Forming new substances is this kind of change.
What is a chemical change?
200
The columns in the periodic table.
What is a group?
300
It is the least dense phase of matter you know.
What is a gas?
300
What fire is (instead of an element).
What is a chemical reaction.
300
JJ Thomson's cathod ray tube experiments conclusively showed that atoms are made of these.
What are charged particles?
300
Silver nitrate and copper react to make copper nitrate and silver. (type of reaction)
What is a single replacement reaction?
300
The number of these is the atomic number.
What are protons?
400
The super heated state of matter in which matter is completely ionized.
What is plasma?
400
Earth is this type of substance.
What is a heterogeneous mixture?
400
Rutherford's experiment with the gold foil provided strong evidence for the existence of this.
What is the nucleus?
400
Hydrogen and oxygen make water.
What is a synthesis reaction?
400
Mendeleev arranged the elements according to this.
What is average atomic mass?
500
When matter changes from solid to liquid without first changing to a liquid.
What is sublimation?
500
A cloud consists of minute particles of liquid water suspended in air, therefore a cloud is this type of substance.
What is a colloid?
500
This is why there can be thousands of different atoms but only about a hundred elements.
What are isotopes?
500
Calcium chloride and lead nitrate make calcium nitrate and lead chloride.
What is a double replacement reaction?
500
Elements in the same group have similar physical and chemical properties because they have the same number of them.
