Radium is an alkaline earth metal. Radium was discovered in 1898 by Marie and Pierre Curie (a Polish and French chemist, respectively) [1]. Although is the heaviest member of the alkaline-earth group it is the most volatile. Radon, chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. It's not just that this radioactive element was discovered at the end of the Victorian era in 1898.
Microscopic quantities of radium in the environment can lead to some accumulation of radium in bone tissue. Its atomic symbol Ra, atomic number 88, atomic weight 226, solid at room temperature. Killing cancer cells can help a patient recover from the disease.
This is a list of the 118 chemical elements which have been identified as of 2020. Its radiation can also kill healthy cells. The most stable isotope is radium-226, with a half-life of about 1600 years. Radium loses about 1% of its activity in 25 years, being transformed into elements of lower atomic weight. Radium is luminescent, corrodes in water to form radium hydroxide. Image Ref.Radium was discovered in 1898 in Paris, by Marie S. Curie and her husband Pierre in pitchblende (mainly uranium dioxide, UO.About eight tons of pitchblende made up of 50 percent uranium oxides is needed to extract 1 gram of radium.This was the Curie’s second major discovery in 1898; earlier that year they discovered,Now, in radium – in the form of radium bromide – they had discovered a further radioactive element whose chemistry was very similar to that of group II metal.Metallic radium was first isolated in 1910 by Marie Curie and Andre Debierne by the electrolysis of a solution of pure radium chloride.The element’s name comes from the Latin word ‘radius’ meaning ray, after the rays emitted by this radioactive element.With the discovery and understanding of radioactivity, chemists realized that one of alchemy’s dreams – the transmutation of elements – was possible.Radium is highly radioactive and hence carcinogenic. The chemical element radium is classed as an alkali earth metal.
