4.7 Nuclear Energy Flashcards
1
Q
Define
Electron volt
A
The kinetic energy possessed by an electron accelerated from rest through a voltage of one volt.
2
Q
Equation
Equivalence of mass & energy
A
E = mc2
3
Q
Define
Binding energy
A
The energy required to separate a nucleus into its constituent nucleons.
4
Q
Define
Fission
A
A heavy nucleus splits into two lighter nuclei of higher binding energy per nuclein and energy is released.
5
Q
Define
Fusion
A
Two light nuclei join together, to form a more massive nucleus of higher binding energy per nucleon, and energy is released.
6
Q
Define
Mass defect
A
The difference between the mass of the separated nucleons and the combined mass of the nucleus.
