**Calculate the Number of Neutrons of \( ^{209}\text{Bi} \)**

To determine the number of neutrons in an isotope, you can use the following formula:

\[ \text{Number of Neutrons} = \text{Mass Number} - \text{Atomic Number} \]

For bismuth (\( ^{209}\text{Bi} \)), the mass number is \(209\), and the atomic number (number of protons) for bismuth is \(83\).

Thus, the number of neutrons is:

\[ 209 - 83 = 126 \]

**Interactive Section:**

- A field labeled "neutrons" where students can input their answer.
- Controls to submit or reset the input (indicated by 'X' for clear and a circular arrow for reset).

This explanation helps students understand how to calculate neutrons in isotopes, using bismuth as an example.
