Transcribed Image Text:### Question
A particle with a +2 charge when produced during the decay of a radioactive element is:
- ○ a proton
- ○ a positron
- ○ a deuteron
- ○ a beta particle
- ○ an alpha particle
### Explanation
This multiple-choice question focuses on identifying the particle with a +2 charge that is emitted during radioactive decay. The correct answer is "an alpha particle," which consists of two protons and two neutrons, resulting in a net positive charge of +2.
### Additional Information
- **Proton:** A subatomic particle with a charge of +1.
- **Positron:** The antimatter counterpart of an electron, with a charge of +1.
- **Deuteron:** The nucleus of deuterium, an isotope of hydrogen, consisting of one proton and one neutron.
- **Beta particle:** An electron or positron emitted during beta decay, with a charge of -1 or +1 respectively.
Alpha particles are commonly emitted in the radioactive decay of heavy elements such as uranium and radium.
Expert Solution

Step 1
