On 18 july 1898, they announced their discovery of polonium (named in honour of marie curie’s homeland) and on 26 december of the same year, they announced their discovery assisted by gustave bémont, of the second new element, which they called radium. In their work with pitchblende, the curies next identified radium (named after the latin word for ray). The citation by the nobel committee was, “in recognition of her services to the advancement of chemistry by the discovery of the elements radium and polonium, by the isolation of radium and the study of the nature and compounds of this remarkable element.”
It was the first element to be discovered in this way Polonium, marie's dear polonium, number 84 on the periodic chart, was the first element discovered via its radioactivity However, within eight months in 1898 she discovered two elements, polonium and radium, founding a new scientific field—radioactivity.
Polonium was discovered by marie and pierre curie in 1898 in paris
The story began in 1896 when henri becquerel discovered radioactivity Inspired by his findings, marie curie decided to investigate uranium radiation as a potential field of research for her doctoral thesis. In july 1898, the curies announced the discovery of polonium In december of the same year, in a note signed by the curies and gustave bémont, they informed the scientific community of the existence of a second element with a promising future
On july 18, 1898, the world witnessed a monumental scientific breakthrough as marie and pierre curie announced the discovery of a new element They proposed to call this remarkable element “polonium,” in honor of marie’s native country, poland. That same month, marie, joined now by her husband, began attempting to isolate the source of that extra energy By july, the pair published a joint paper announcing the discovery of a new and far more radioactive element, which they named polonium, after marie's home country.
Finally, the curies discovered polonium in july 1898, several months before their more famous discovery of radium
The discovery paper was presented to the french academy of sciences on july 18, 1898, marking the first new element discovered through radioactivity.
