Question
What are the half-life (t1/2) and decay constant (upside down y) of a radioactive material?
Answers below:
The decay constant is the time it takes for half the mass of the radioactive material to decay, and the half-life is the probability that a given nucleus in the material will decay per unit of time.
The half-life is the time it takes for the radioactive material to decay completely, and the decay constant is the probability that a given nucleus in the material will decay per unit of time.

The correct definitions are:
- **Half-life (t₁/₂)**: The half-life is the time it takes for half the mass of the radioactive material to decay.
- **Decay constant (λ)**: The decay constant is the probability that a given nucleus in the material will decay per unit of time.
So, the accurate answer from the provided choices is: **"The half-life is the time it takes for half the mass of the radioactive material to decay, and the decay constant is the probability that a given nucleus in the material will decay per unit of time."**
- **Half-life (t₁/₂)**: The half-life is the time it takes for half the mass of the radioactive material to decay.
- **Decay constant (λ)**: The decay constant is the probability that a given nucleus in the material will decay per unit of time.
So, the accurate answer from the provided choices is: **"The half-life is the time it takes for half the mass of the radioactive material to decay, and the decay constant is the probability that a given nucleus in the material will decay per unit of time."**
