nuclear Flashcards
1
Q
nucleon
A
protons and neutrons together
2
Q
rest energy
A
intrinsic amount of energy that is associated with mass
3
Q
strong force
A
overcomes repulsive coulomb forces b/w protons in nucleus and hold it together: 10^38 times stronger than gravity, only effective over very short distances
4
Q
valley of stability
A
<83 : more neutrons are needed to be added to stabilize, but they don’t fit
5
Q
binding energy
A
difference in energy between bound by leans and unbound protons and neutrons
6
Q
alpha decay
A
results in a He2 mass 4, and then another element you get from subtraction
7
Q
beta decay
A
results in an electron and another element
