1898: Radium & Polonium. The longest lived, and most common, isotope of radium is 226 Ra with a half-life of 1600 years. Radium (88 Ra) has no stable or nearly stable isotopes, and thus a standard atomic weight cannot be given. RCMP is appealing to the public for help in the investigation of the death of a 35-year-old woman, whose body was discovered in Kootenay National Park last … Radium was discovered by Nobel laureate Marie Curie and her husband Pierre in 1898. The color … Radium was particularly intriguing because it glowed in the dark, and as Marie noted, “These gleamings seemed suspended in the darkness [and] stirred us with ever-new emotion and enchantment” (Moore). Marie and Pierre Curie discover the radioactive elements radium and polonium. Tantalus was a king in greek mythology who, after stealing secrets from the gods, was punished by being forced to stand in a pool of water that flowed away … Marie Curie was a physicist and chemist who became the first woman to win a Nobel prize. Curie discovered radioactivity, and, together with her husband Pierre, the radioactive elements polonium and radium while working with the mineral … The Nobel Prize in Chemistry 1911 was awarded to Marie Curie, née Sklodowska "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". Along with her husband Pierre, she discovered two elements: polonium and radium. Radium has 33 known isotopes from 202 Ra to 234 Ra. The first x-ray picture is an image of his wife's hand. 226 Ra occurs in the decay chain of 238 U (often referred to as the radium series). It was quickly put to use as a cancer treatment. Wilhelm Roentgen discovers x-rays. Tantalum was discovered by the Swedish chemist Anders Ekeberg, who extracted the metal from mineral samples. Beginning in 1918, the Radium Institute at the University of Paris began to operate under Curie’s direction and from its inception was a major center for chemistry and nuclear physics. B.C. In 1898, Marie and Pierre Curie, two of the most prominent pioneers in researching radioactivity, discovered the element radium. .
