Alpha particle has
Correct answer: B. High ionization and Less Penetration
- A. Less ionization and High Penetration
- B. High ionization and Less Penetration
- C. High ionization and High Penetration
- D. Less ionization and Less Penetration
Explanation
Alpha particles are relatively large and heavy, consisting of two protons and two neutrons. This makes them highly ionizing, meaning they are very effective at knocking electrons off atoms and creating ions. However, due to their size and charge, they have a short range and are easily stopped by a thin sheet of paper or even a layer of air. This means they have low penetration power.

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.
