discoverer of radium & polonium

Post  bejoy on Tue Nov 15, 2016 6:34 am

Polonium is chemically resembles bismuth element and was found as a fraction of the bismuth sulfide in pitchblende ore. Polonium-210 is the only naturally occurring isotope. Polonium widely used in space probes heaters, antistatic devices, and sources of neutrons and alpha particles. Chemical properties of polonium like it dissolve readily in dilute acids, but slightly soluble in alkalis. Polonium solutions are first colored in pink by the Po2+ ions, but then rapidly become yellow because alpha radiation from polonium ionizes the solvent and converts Po2+ into Po4+. http://bit.ly/2fBBbHI
