Notes

  1. ↑ The most stable isotope of livermorium cannot be determined based on existing data due to uncertainty that arises from the low number of measurements. The half-life of 293Lv corresponding to two standard deviations is, based on existing data, 57+86
    −34     milliseconds, whereas that of 291Lv is 19+34
    −12     milliseconds; these measurements have overlapping confidence intervals.[1]
