The half life period of the radioactive is `_15P^30` is

Options

A. 6.5 minutes
B. 3.25 minutes
C. 10 minutes
D. 8.4 minutes

Answer

To find the half-life period of the radioactive isotope \( _{15}P^{30} \), we can follow these steps:

### Step 1: Understand the Concept of Half-Life
Half-life is defined as the time required for half of the radioactive substance to decay. This means if you start with a certain amount of a radioactive substance, after one half-life, only half of that amount will remain.

### Step 2: Identify the Given Information
From the problem, we know that the half-life period of radioactive phosphorus (\( _{15}P^{30} \)) is given.

### Step 3: State the Half-Life Value
The half-life of \( _{15}P^{30} \) is provided as 3.25 minutes.

### Step 4: Conclusion
Thus, the half-life period of radioactive phosphorus \( _{15}P^{30} \) is 3.25 minutes.

### Final Answer
The half-life period of radioactive phosphorus \( _{15}P^{30} \) is **3.25 minutes**.
