Marie curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it she reasoned that pitchblende must contain at least one other radioactive element. Radium is a highly radioactive chemical element classified among the alkaline earth metals of the periodic table of elements this element has several research uses, and historically it was used in a wide range of industries.
Radium now has few uses, because it is so highly radioactive radium-223 is sometimes used to treat prostate cancer that has spread to the bones because bones contain calcium and radium is in the same group as calcium, it can be used to target cancerous bone cells. Polonium: polonium (po), a radioactive, silvery-gray or black metallic element of the oxygen group (group 16 [via] in the periodic table) the first element to be discovered by radiochemical analysis, polonium was discovered in 1898 by pierre and marie curie, who were investigating the radioactivity of a. Radium: a rare, brilliant white, luminescent, highly radioactive metallic element found in very small amounts in uranium ores, having 13 isotopes with mass numbers between 213 and 230, of which radium 226 with a half-life of 1,622 years is the most common.
Radium is a highly radioactive alkali earth metal, and, though some of the elements from this chemical group are critical for life (if you don't have them you die), this one is to be avoided if it .

The description of the highly radioactive element radium
Radium / ˈreɪdɪəm / n a highly radioactive luminescent white element of the alkaline earth group of metals it occurs in pitchblende, carnotite, and other uranium ores, and is used in radiotherapy and in luminous paints. An element all of whose isotopes spontaneously transform into one or more different nuclides, giving off various types of radiation examples include promethium, radium, thorium, and uranium technetium (atomic number 43), promethium (61), polonium (84), and all the elements that follow it in the . Radium is responsible for much of the radioactivity of uranium ores uranium is radioactive too, but radium is much, much more intensely radioactive, so even tiny amounts in an ore can greatly increase its overall radioactivity.
- It was the most radioactive element that could be seen and weighed bayard’s alarm-clocks in the 1950's one of the first uses of radium was to make luminous the figures on the dials of clocks, alarm clocks and compasses.
- The radium is a rare chemical element that carries the atomic number 88 the white, luminous metal is known for its highly radioactivity the radioactive elements are known for their unseen radioactive rays.
