What is mass defect?
Difference between the mass of the nucleus and the mass of its constituents (mass of nucleus is less)
1 of 10
What is Einstein’s equation?
E=mc^2
2 of 10
What does Einstein’s equation assume?
That energy and mass are equivalent
3 of 10
What happens when nucleons are joined together?
Total mass decreases, lost mass is converted in to energy and released, the amount of energy released is the mass defect
4 of 10
How much energy would you need to pull apart a nucleus?
The energy which was released to join the nucleus (mass defect)
5 of 10
What is the binding energy?
Energy needed to separate all nucleons in a nucleus which is equivalent to the mass defect
6 of 10
What is one atomic mass equivalent to?
931.5 MeV
7 of 10
How do you work out the binding energy per nucleon?
Binding energy per nucleon = (Binding energy AKA mass defect)/ nucleon number
8 of 10
What is the most stable nucleus?
Iron which has nucleon number 56
9 of 10
What does a high binding energy mean?
A more stable nucleus
