Na is the only stable (and the only primordial) isotope. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2). Sodium has two radioactive cosmogenic isotopes ( 22. Na, half-life = 2.605 years; and 24. Na, half-life ≈ 15 hours).

Sodium-22 undergoes electron capture according to the following nuclear equation: ""_-1^0"e" + _11^22"Na" -> _10^22"Ne" Notice that the electron capture of Na-22 results in nuclear transmutation; the inner-orbital electron is captured by the nucleus, the result being the formation of a neutron from the combination of said electron with a proton from the nucleus.
