Physics · Alpha-particle scattering experiment, Rutherford's model of atom
Which row describes the nature of - particles and of rays
Which row describes the nature of \( \alpha \) - particles and of \( \gamma- \) rays
- A. \( \alpha \) - particles : helium nuclei ; rays - electromagnetic radiation
- B. \( \alpha \) - particles : helium nuclei ; \gamma rays - electrons
- C. \( \alpha \) - particles: protons; \( \gamma \) rays - electromagnetic radiation
- D. \( \alpha \) - particles: protons; \( \gamma \) rays - electrons
Step-by-step solution
α-particles are helium nuclei (2 protons + 2 neutrons), and γ-rays are high-energy electromagnetic radiation. Option A correctly identifies both. Options B, C, and D misrepresent either α-particles as protons or γ-rays as electrons.
