Tin: isotope data

Tin has the most stable isotopes (10) of all elements. Tin isotopes are used in a variety of applications. Sn-112 is used as precursor in the production of the radioisotope Sn-113 while Sn124 is used for producing Sb-124. Sn-116 and Sn-117 can both be used for the production of the medical radioisotope Sn-117m which is used in treating bone cancer. Both Sn-118 and Sn-119 have been evaluated for the production of Sn-119m.

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 tin are listed (including any which occur naturally) below.
Isotope Mass / Da Natural abundance (atom %) Nuclear spin (I) Magnetic moment (μ/μN)
112Sn 111.904826 (5) 0.97 (1) 0
114Sn 113.902784 (4) 0.66 (1) 0
115Sn 114.903348 (3) 0.34 (1) 1/2 -0.91884
116Sn 115.901747 (3) 14.54 (9) 0
117Sn 116.902956 (3) 7.68 (7) 1/2 -1.00105
118Sn 117.901609 (3) 24.22 (9) 0
119Sn 118.903311 (3) 8.59 (4) 1/2 -1.04729
120Sn 119.9021991 (29) 32.58 (9) 0
122Sn 121.9034404 (30) 4.63 (3) 0
124Sn 123.9052743 (17) 5.79 (5) 0

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 tin are listed above. This table gives information about some radiosotopes of tin, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments.

Sheffield ChemPuter isotope pattern calculator

You can use WebElements to calculate an isotope pattern for an arbitrary chemical formula:

Edit this formula :

Note the following when entering your formula:

  • Correctly nested brackets [{()}] are OK
  • 'Pseudoelements' such as Me, Ph, Cp, and many others are OK
  • Compound names and element names such as 'water' or 'manganese' are not OK
  • Experiment with your formula to see what is possible
