There are three kinds of subatomic particles that commonly exist in nature: 
protons, neutrons and electrons. There are many others, but they are not 

Protons and neutrons are bags of quarks (three each) held together by 
gluons. Protons and neutrons are not round, but instead lumpy-- although 
it's rather hard to really see what shape they are. They are very small (10^
-12 meters across!).

Quarks and electrons are, to the best of our knowledge, point particles. 
That  means they are as small as you can get! Nothing makes them up. We are 
doing experiments to see if that is true.
