How many stable isotopes does beryllium have
Web17 okt. 2010 · 3: Beryllium with 5 neutrons is stable, while 4 and 6 neutrons are not, and almost never occur naturally. Webisotopes of polonium are known, none of which are stable. Its four longest lived isotopes are: polonium-206 (8.8 days), polonium-208 (2.898 years), polonium-209 (102 years), and polonium-210 (138 days). Polonium-210 is the predominant naturally occurring isotope and the one most widely used. WHAT IS POLONIUM-210 USED FOR?
