1. The Discovery of Radium
Marie Curie’s name is synonymous with the study of radioactivity, a term she coined herself. Her groundbreaking work, alongside her husband Pierre Curie, not only discovered radium but also laid the foundation for our understanding of radiation and its myriad applications.
In December 1898, the Curies announced the existence of radium, an element that would forever change the trajectory of science and medicine.
Marie Curie’s Role in Radioactivity Research
Marie Curie’s relentless pursuit of knowledge began with the study of uranium rays, which were discovered by Henri Becquerel.
Through meticulous research, she found that the rays remained constant, regardless of the condition or form of the uranium. This observation led to the revolutionary idea that the rays were emanating from the element’s atomic structure—a property she named “radioactivity.”
Marie Curie’s contribution was pivotal; she unearthed fundamental truths about atomic physics, setting the stage for future discoveries.
How Marie Curie Discovered Radium?
Marie Curie’s discovery of radium began with her study of uranium. She observed that the rays emitted by uranium remained constant, regardless of its condition or form. This led her to believe that the rays were coming from within the atomic structure of the element itself, which she called “radioactivity.”
Curie realized that there must be other elements with similar properties, and she began searching for them. She initially focused on pitchblende, a mineral that contains uranium, but found that it was more radioactive than could be explained by the presence of uranium alone.
This led her to conclude that there must be other radioactive elements present in the pitchblende.
To isolate these elements, Curie developed a laborious process of grinding the pitchblende into a fine powder, dissolving it in acid, and then precipitating out different fractions of the solution.
Through this process, she was able to isolate two new elements: polonium and radium.
The Breakthrough Discovery
The path to discovering radium was arduous, involving the processing of tons of pitchblende, a mineral-rich in uranium, yet more radioactive than uranium itself could account for. This discrepancy hinted at something remarkable.
The Curies postulated the presence of another radioactive element, which they painstakingly isolated in 1898. They named it radium, derived from the Latin word for “ray”.
Its intense radioactivity made it stand out, and it soon became apparent that radium had properties that could revolutionize science.
