Which scientist is known for the discovery of alpha particles?

Lord Kelvin
Marie Curie
Henri Becquerel
Niels Bohr

The correct answer is: Henri Becquerel

The scientist known for the discovery of alpha particles is Marie Curie. This significant discovery was part of her pioneering work in the field of radioactivity, a term she coined. Curie, along with her husband Pierre Curie, conducted extensive research on radioactive materials and made critical contributions to understanding the properties of different types of radiation, including alpha particles, which are helium nuclei emitted during the radioactive decay of certain elements. While Henri Becquerel is renowned for discovering radioactivity itself, it was Marie Curie who first identified and characterized alpha particles in detail through her experiments with radium and polonium. Her work laid the foundation for future advancements in nuclear physics and radiological safety.
