200
All matter is composed of these fundamental substances
What are Elements
200
Three common forms of radiation
What are Alpha, Beta, and Gamma rays
200

300
When two or more atoms bond to form a more complex structure
What is Synthesis
300
Serve as structural materials, energy source, or hormones.
What are Proteins
400
Atoms can combine with atoms like themselves or with other atoms by forming these types of attractions
What are Chemical Bonds
400
The electrons of an atom occupy one or more areas of space
What are shells
400
