As far as I know, he did not propose any atomic model worthy of the name. He studied phosphorescence and discovered radioactivity by accident.
Antoine Henri Becquerel, a French physicist, is primarily known for his discovery of radioactivity. However, he did not propose a specific atomic model. Instead, his work focused on studying the behavior of radioactive materials, specifically uranium salts. It was his accidental discovery of radioactivity in 1896 that ultimately laid the foundation for the atomic models proposed by later scientists, such as J.J. Thomson, Ernest Rutherford, and Niels Bohr. These scientists made significant contributions to our understanding of atoms and their structures. So, while Becquerel did not propose an atomic model himself, his work had a profound impact on the development of modern atomic theory.
