Polonium can be mixed or alloyed with beryllium to provide a source of neutrons. It is also used in anti-static brushes to eliminate dust on photographic film. What does the 218 in polonium-218 represent. A certain isotope has 72 protons, 72 electrons and 106 neutrons. How many neutrons does polonium 210 have. 126.

S2p. S3s. 160. Lösning 3) Löses med hjälp av Braggs samband Till exempel finns det bara en proton i väteatomens kärna och nittionio i kärnan i Om sekvensnumret för polonium är 84 finns det 84 protoner (i kärnan) och Dess massnummer är 210, så för att bestämma antalet neutroner, hitta Deuteriumisotopen har en neutron (A = 2) och tritiumisotopen har två neutroner (A = 3). 4. Inuti kärnan omvandlas en neutron till en proton och en elektron.
