Correct answer: D. Helium
- A. Hydrogen
- B. Deuterium
- C. Tritium
- D. Helium
- E. Lithium
Explanation
Alpha particle has charge of +2e and mass no 4Hydrogen has a charge of +e and mass no 1Deutrium has charge of +e and mass no 2Tritrium has charge of +e and mass no 3Helium has charge of +2e and mass no 4 Lithium has charge of +3e and mass no 7This confirms that alpha rays are same as the Helium Nuclei.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
