Radiodecay Flashcards
1
Q
What is the half-life of nuclides given by?
A
t = 0.693/k, where k is the constant rate of decay (which can differ between isotopes and elements)
2
Q
What are nuclides with short half-lives?
A
Nuclides with large constant decay rates and short half-life time spans (tend to be more unstable)
3
Q
What are nuclides with long half-lives?
A
Nuclides with small constant decay rates and long half-life time spans (tend to be more stable)
4
Q
What function does radio decay form?
A
Exponential decay
5
Q
What is half-life?
A
The time it takes for the number of radioactive particles to be multiplied by 1/2 once
