Bismuth - 83Bi: isotope data

Naturally occurring isotopes

This table shows information about naturally occuring isotopes, their atomic masses, their natural abundances, their nuclear spins, and their magnetic moments. Further data for radioisotopes (radioactive isotopes) of bismuth are listed (including any which occur naturally) below.
Isotope Mass / Da Natural abundance (atom %) Nuclear spin (I) Magnetic moment (μ/μN)
209Bi 208.980374 (5) 100 9/2 4.1106
Isotope abundances of bismuth
Isotope abundances of bismuth. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. This is not to be confused with the relative percentage isotope abundances which totals 100% for all the naturally occurring isotopes.

Radiosotope data

Further data for naturally occuring isotopes of bismuth are listed above. This table gives information about some radiosotopes of bismuth, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments.
Isotope Mass / Da Half-life Mode of decay Nuclear spin Nuclear magnetic moment
205Bi 204.97737 15.31 d EC to 205Pb 9/2 4.16
206Bi 205.97848 6.243 d EC to 206Pb 6 4.60
207Bi 206.97846 35 y EC to 207Pb 9/2 4.08
208Bi 207.97973 3.68 x 105 y EC to 208Pb 5
210Bi 209.98410 5.01 d β- to 210Po; α to 206Tl 1 -0.0445
