Question

An experiment is set up to determine the type of radioactive decay coming from a certain hazardous nuclide. The analytical instrument used in this experiment detects the charge of the particles emitted from the nuclide. When interpreting the results of the experiment, it was discovered that the emitted particles had no charge at all. Which of the following could be the identity of these particles?

Select the correct answer below:

Positrons

Protons

γ particles

β particles

Answer 1

The particles are γ particles. γ particles have no charged, they are neutral species.

But positrons and protons are positively charged. They have +1 charge.

β particles are negatively charged. They have -1 charge.
