Which of the following rays consists of positively charged particles?

Correct option is C

​​Correct Answer:(c) Alpha rays​

Alpha rays consist of positively charged particles called alpha particles. These particles are composed of two protons and two neutrons (similar to a helium nucleus) and are emitted during radioactive decay processes, such as the decay of heavy elements like uranium or radium. Because alpha particles have a positive charge, they are deflected by magnetic and electric fields.

Information Booster:
● Nature of Alpha Rays: Heavily charged and relatively massive compared to other forms of radiation.
● Penetration Power: Low penetration; stopped by paper or skin.
● Ionizing Power: High ionizing ability due to their charge and mass.
● Source: Emitted during the radioactive decay of heavy nuclei (alpha decay).
● Applications: Used in smoke detectors and medical treatments like cancer therapy.

Additional Knowledge:

• (a) Beta rays: Consist of negatively charged electrons (β⁻) or positively charged positrons (β⁺), depending on the type of beta decay.
• (b) Gamma rays: Electromagnetic radiation with no charge or mass, emitted alongside alpha or beta particles.
• (d) X-rays: High-energy electromagnetic waves with no charge, commonly used in medical imaging.
• (c) Alpha rays: Correct, as they consist of positively charged particles (helium nuclei).
