Flashcards
Binding energy and fission
Cards in this deck (17)
- 1How much mass do free nucleons have compared to nucleons gathered in the nucleus?Free nucleons have more mass
- 2What is this loss in mass changed into?Energy
- 3What is the binding energy?The amount of work needed to seperate a nucleus into its components
- 4What would you have to overcome to deconstruct a nucleus?The nuclear strong force
- 5What happens when a nucleus is formed?The nuclear strong force pulls the nucleons together and so does work
- 6What is the energy released from the nuclear strong force pulling the nucleus together equal to?The binding energy
- 7What must be effected if energy is being released when a nucleus is formed?Mass
- 8What 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
- 9What is this difference in mass between the nucleus and components called?Mass defect
- 10What is mass defect the mass equivalent of?The binding energy
- 11What does a binding energy graph look like for fusion and fission?
- 12What does a binding energy curve show us?A plot of binding energy per nucleon against number of nucleons in the nucleus
- 13Between sodium and hydrogen what happens to the binding energy?It increases with the number of nucleons
- 14what does this show us?That we can get a lot of energy by combing to small nuclei
(Nuclear fusion) - 15At what point are the nuclei most stable?Where the graph begins to level out
- 16What are the most stable nuclei?Nickel-62
Iron-58
Iron-56 - 17Due to their stability what are these often the most prevalent products of?Supernovae
