Isotopes of nobelium : ウィキペディア英語版 | Isotopes of nobelium Nobelium (No) is a synthetic element, and thus a standard atomic mass cannot be given. Like all synthetic elements, it has no stable isotopes. The first isotope to be synthesized (and correctly identified) was 254No in 1966. There are 12 known radioisotopes, which are 250No to 260No and 262No, and 3 isomers, 251mNo, 253mNo, and 254mNo. The longest-lived isotope is 259No with a half-life of 58 minutes. The longest-lived isomer is 251mNo with a half-life of 1.7 seconds. == Table ==
