Caption: Radium (Ra). Diagram of the nuclear composition and electron configuration of an atom of radium-226 (atomic number: 88), the most stable isotope of this element. The nucleus consists of 88 protons (red) and 138 neutrons (blue). 88 electrons (green) bind to the nucleus, successively occupying available electron shells (rings). Radium is a radioactive alkaline earth metal in group 2, period 7, and the s-block of the periodic table. Formed in uranium ores, the Curies discovered it in 1898. Radium-226, once used in watches, has a half-life of 1061 years, with the unstable nucleus emitting an alpha particle to form radon-222.
