Sodium: isotope data
Naturally occurring isotopes
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.
Further data for naturally occuring isotopes of sodium are listed above. This table gives information about some radiosotopes of sodium, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments.
||Mass / Da
||Mode of decay
||Nuclear magnetic moment
||EC to 21Ne
||EC to 22Ne
||β- to 24Mg
||β- to 25Mg
||β- to 26Mg
