Homework

• Activity 12 A, p.194, Mass-Energy Equivalence
• Activity 12B, p.100-200, Nuclear Reactions
• Start Practice Assessment for Atomic & Nuclear Physics

Nuclear Fission

• The breaking up of a larger nucleus into smaller nuclei
• The decrease in mass per nucleon, matches the increase in binding energu per nucleon
• This binding energy per nucleon is a negative energy and represents energy that is lost (radiated away) during the reaction. 
• Binding energy per nucleon also represents the energy that would need to be added to liberate a nucleon from the nucleus

Nuclear Fission

Fission & Fusion

Nuclear Fusion

• The joining of smaller nuclei into a larger nucleus
• The decrease in mass per nucleon, matches the increase in binding energu per nucleon
• This binding energy per nucleon is a negative energy and represents energy that is lost (radiated away) during the reaction. 
• Binding energy per nucleon also represents the energy that would need to be added to liberate a nucleon from the nucleus
