Alpha particles are __________.
- Atwice the mass of beta particles
- Bnegatively charged
- Cjust like helium nuclei
- Dlower in ionizing power as compared to gamma rays
Solution & Step-by-step Explanation
Alpha particles consist of two protons and two neutrons bound together, making them just like helium nuclei (He
2+
). They are positively charged and carry a much higher mass and ionizing power than beta particles and gamma rays.
