![]() ![]() Atomic number (number of protons in the nucleus): 88.There are several known isotopes of radium, but due to the rapid decay rates of many of the isotopes, it is uncertain about the natural abundances of the radium isotopes. Trace amounts of radium are found in uranium ore, because radium is created from the decay of the uranium atom, which then into several other unstable elements before finally ending in the element lead. ET/PT.Radium has an abundance of about 1 part per trillion in the Earth's crust, according to Chemicool.

Though the long, poisonous task of separating the elements would ultimately cleave the couple, for now the arduous work bound them together.” On the cover of one black canvas laboratory log, the initials ‘M’ and ‘P’ before the surname Curie are scripted directly one atop the other, as if to pull apart even just the letters of their names would be too brutal. Their handwritings intermingle in their notebooks. “With the constant companionship that accompanied their research, the Curies’ love deepened. “After four years of steady labor, four hundred tons of water, and forty tons of corrosive chemicals, on March 28, 1902, they managed to extract one tenth of a gram of radium chloride. The University gave the Curies a dilapidated wooden shed previously used for human dissection. They asked the Sorbonne for laboratory space to complete the work. Procuring seven tons of pitchblende-a mountain of black rubble strewn with pine needles-from the Bohemian mines, they began trying to extract measurable amounts of their new elements. “And so, the Curies plunged into a Sisyphean task. Chemists in particular wanted to see them, to touch them.Only concrete evidence would be persuasive. ![]() ![]() “The Curies had demonstrated the existence of polonium and radium through their radioactivity, but fellow scientists remained skeptical. Here Redniss describes how, following Marie’s observation of radioactivity in a mineral called pitchblende, the Curies isolated for the first time a compound containing radium, a radioactive element. But it finds new life in the hands of writer and artist Lauren Redniss, who weaves together deft narrative and vivid illustrations to create a thoroughly modern account of the scientific and romantic passions of the Curies, as well as the repercussions of their discoveries. The story of Marie and Pierre Curie and their Nobel Prize–winning research on radiation has been oft told. Radioactive: Marie & Pierre Curie, a Tale of Love and Fallout ![]()
