The table below details the nature of alpha (α\alphaα) particles and beta-minus (β−\beta^-β−) particles:
| Radiation Type | Nature |
|---|---|
| Alpha (α\alphaα) | Helium nucleus |
| Beta-minus (β−\beta^-β−) | High-speed electron |
Explain, in terms of their physical properties and interactions with matter, why alpha particles and beta-minus particles have different ionizing and penetrating powers.
