Radium chemistry
WebRadium is a chemical element with atomic number 88 which means there are 88 protons and 88 electrons in the atomic structure. The chemical symbol for Radium is Ra. Pure radium is silvery-white alkaline earth metal. All isotopes of radium are highly radioactive, with the most stable isotope being radium-226. ... WebMar 14, 2024 · radon (Rn), chemical element, a heavy radioactive gas of Group 18 ( noble gases) of the periodic table, generated by the radioactive decay of radium. (Radon was originally called radium emanation.) Radon is a colourless gas, 7.5 times heavier than air and more than 100 times heavier than hydrogen.

Radium, like barium, is a highly reactive metal and always exhibits its group oxidation state of +2. It forms the colorless Ra cation in aqueous solution, which is highly basic and does not form complexes readily. Most radium compounds are therefore simple ionic compounds, though participation from the … See more Radium is a chemical element with the symbol Ra and atomic number 88.
