Isotopes of seaborgium
Seaborgium (106Sg) is a synthetic element and so has no stable isotopes. A standard atomic weight cannot be given. The first isotope to be synthesized was 263Sg in 1974. There are 13 known radioisotopes from 258Sg to 271Sg and 4 known isomers (259mSg, 261mSg, 263mSg, and 265mSg). The longest-lived isotope is 269Sg with a half-life of 14 minutes.
