The mass of α-particle is:
Correct answer: C. 2 Mp + 2Mn
- A. 4Mp
- B. 4Mn
- C. 2 Mp + 2Mn
- D. 2 Me + 2Mp
Explanation
α-particles are Helium nuclei. The charge on them is +2e while their mass is 4 amu that is every α-particle has two protons and two neutrons.Mass of a-particle = 2 Mp + 2Mn

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.
