| Question | Answer |
| How much mass do free nucleons have compared to nucleons gathered in the nucleus? | Free nucleons have more mass |
| What is this loss in mass changed into? | Energy |
| What is the binding energy? | The amount of work needed to seperate a nucleus into its components |
| What would you have to overcome to deconstruct a nucleus? | The nuclear strong force |
| What happens when a nucleus is formed? | The nuclear strong force pulls the nucleons together and so does work |
| What is the energy released from the nuclear strong force pulling the nucleus together equal to? | The binding energy |
| What must be effected if energy is being released when a nucleus is formed? | Mass |
| What can you find about the mass of the nucleus and the mass of the components of the nucleus? | The mass of the components of the nucleus is greater |
| What is this difference in mass between the nucleus and components called? | Mass defect |
| What is mass defect the mass equivalent of? | The binding energy |
| What does a binding energy graph look like for fusion and fission? | |
| What does a binding energy curve show us? | A plot of binding energy per nucleon against number of nucleons in the nucleus |
| Between sodium and hydrogen what happens to the binding energy? | It increases with the number of nucleons |
| what does this show us? | That we can get a lot of energy by combing to small nuclei (Nuclear fusion) |
| At what point are the nuclei most stable? | Where the graph begins to level out |
| What are the most stable nuclei? | Nickel-62 Iron-58 Iron-56 |
| Due to their stability what are these often the most prevalent products of? | Supernovae |
