This category contains eight valence electrons on each element.
What is the noble gases?
100
This has no definite shape.
What is gas?
100
All matter is made of this.
What is atoms?
100
This field of chemistry is the concern with the heat changes that occur during chemical reactions.
What is thermochemistry?
100
These are the two main types of mixtures.
What is homogeneous and heterogeneous?
200
This group is the most reactive nonmetals.
What is halogens?
200
Stars are an example of this.

200
It is the quantity of heat needed to raise 1g of water by 1 degree Celsius.
What is calorie?
200
These properties do depend on the amount of matter present.
What is extensive?
300
Transition metals are in this block.
What is d block?
300
This is a physical blend of two or more substances.
What is a mixture?
300
Electrons are found in discrete locations around a nucleus called these.
What are shells?
300
The heat absorbed by one mole of a substance in melting.
What is heat of fusion?
300
These properties do not depend on the amount of matter present.
What is intensive?
400
This is the tendency of an atom to attract electrons when combined with other atoms.
What is electronegative?
400
This is a homogeneous mixture.
What is a solution?
400
To name isotopes, you must first write the element name followed by this.
What is mass number?
400
The heat change caused by dissolution of one mole of a substance.
What is the molar heat of solution?
400
This occurs when the chemical composition of a substance changes.
What is chemical change?
500
This is the change in energy that occurs when an electron is acquired by a neutral atom.
What is electron affinity?
500
Any part of a system with uniform composition and properties is called this.
What is a phase?
500
In 1926 Erwin Schrodinger developed the model of this.
What is quantum mechanical?
500
This is the measurement for measuring heat energy.
What is a joule?
500
This law states that the amount of mass never changes.
What is the law of conservation of mass?
