Describe the rays emitted by radioactive elements.
(N/A) Radioactive elements emit three types of rays: $\alpha$,$\beta$,and $\gamma$. Their characteristics are summarized below:
| Property | $\alpha$-rays | $\beta$-rays | $\gamma$-rays |
|---|---|---|---|
| Nature | Helium nuclei $(He^{2+})$ | High-speed electrons $(e^-)$ | Electromagnetic radiation |
| Charge | $+2$ | $-1$ | $0$ (Neutral) |
| Mass | $4 \ amu$ | Negligible $(1/1837 \ amu)$ | $0$ |
| Penetrating Power | Least | $100$ times more than $\alpha$ | $1000$ times more than $\alpha$ |
