The correct Answer is:
To determine which of the given options consists of charged particles of matter, we will analyze each option based on the nature of the particles they contain. ### Step-by-Step Solution: 1. **Understanding Charged Particles**: - Charged particles of matter include protons (positively charged) and electrons (negatively charged). Neutrons are neutral and do not carry any charge. 2. **Analyzing Each Option**: - **Option 1: Alpha Particles**: - Alpha particles consist of 2 protons and 2 neutrons (which form a helium nucleus). Since protons are positively charged, alpha particles are indeed charged. - **Option 2: Beta Particles**: - Beta particles come in two forms: beta minus (β-) and beta plus (β+). Beta minus particles are electrons (negatively charged), while beta plus particles are positrons (positively charged). Therefore, both types of beta particles are charged. - **Option 3: Gamma Rays**: - Gamma rays are electromagnetic radiation and do not consist of charged particles. They are neutral and do not carry any charge. - **Option 4: Anode Rays**: - Anode rays are streams of positively charged particles, typically consisting of positive ions. Therefore, anode rays are also charged. 3. **Conclusion**: - The options that consist of charged particles are: - Option 1: Alpha particles (positively charged) - Option 2: Beta particles (negatively and positively charged) - Option 4: Anode rays (positively charged) ### Final Answer: The options that consist of charged particles of matter are **Option 1 (Alpha particles)**, **Option 2 (Beta particles)**, and **Option 4 (Anode rays)**. ---
