What is synthesis?
100
Name the process of splitting a nucleus into two or more smaller nuclei.
Nuclear Fission
200
This is a general term for a bond where the atoms share electrons.
What is a covalent bond?
200
The name of the scientist who helped to prove Conservation of Mass.
Who is Lavoisier?

The substances on the right of a chemical reaction are called this.
What are products?
200
A reaction where one thing breaks down into many.
What is decomposition?
200
This is the process of two or more nuclei combining to form a nucleus of larger mass.
Nuclear Fusion
300
This is a term for a covalent bond with an uneven sharing of electrons.
What is a polar covalent bond?
300
The compound that the scientist used in order to prove the conservation of mass.
What is water?
300
These are added before chemical substances to balance an equation.
What are coefficients?
300
A reaction where carbon dioxide and water are formed.
What is combustion?
300
These are nuclei that have the same number of protons but different numbers of neutrons.
Isotopes
400
The reason why a compound formed from two elements does not have the same properties as its individual elements.
What is the fact that molecules are rearranged and moved when they bond together?
400
The person who helped Lavoisier with his experiments.
What is his wife?
400
These numbers are never changed when balancing an equation.
What are subscripts?
400
A reaction where a metal is formed such as silver.
What is a single displacement reaction?
400
Name the process when the strong force is not large enough to hold a nucleus together tightly, the nucleus can decay. When a nucleus decays, it emits matter and energy.
Radioactivity

500
The number that is obtained when you add up the coefficients when the following equation is balanced:
Mg + O2 --> MgO
What is 5?
500
A reaction in which two ionic compounds exchange cations (or anions).
What is double displacement?
