Radioactive emissions have distinct characteristics. Which of the following statements correctly com — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Options A, B, and C are true. $\alpha$ -particles carry a $+2$ charge and deflect towards the cathode, while $\beta$ -particles (electrons) deflect towards the anode. $\alpha$ -particles have the highest ionizing power, whereas $\gamma$ -rays have the highest penetrating power. Option D is incorrect because $\beta$ -particles (electrons) have negligible mass compared to massive $\alpha$ -particles (helium nuclei) and travel much faster (closer to the speed of light).
