Zinc - Atomic Radius - Zn - Periodic Table
TīmeklisRadon is the product of the decay of other unstable, radioactive elements such as radium, thorium and actinium. The colourless, odourless, tasteless gas can be isolated from these sources but soon decays as it has no stable isotopes. The early pioneers in the study of radioactivity, the Curies, had noted that radium appeared to make the ... TīmeklisRadon je kemični element, ki ima v periodnem sistemu simbol Rn in atomsko število 86. Ta radioaktivni žlahtni plin nastane z razpadom radija; radon je eden najtežjih plinov in škodljiv zdravju. Najbolj stabilni izotop, Rn-222, ima razpolovno dobo 3,8 dni in se ga uporablja v radioterapiji. Povzroča pljučnega raka . tanne jannice body art marks of identity ncbi
