• neutron 

• moron 

These are found in the nucleus and have a neutral charge. 

• proton 
• electron 
• neutron 
• moron 

These are found outside the nucleus and have a negative charge.

• moron 

These will determine what element an atom is. 

• number of neutrons
• number of electrons
• number of atoms 
• number of protons 

This is how you find the number of neutrons in an atom. 

• Subtract the atomic number from the atomic mass
• Subtract the atomic mass from the atomic number 
• Add the atomic mass to the atomic number 
• Divide the atomic mass by the atomic number
