Notes

↑ The most stable isotope of tennessine cannot be determined based on existing data due to uncertainty that arises from the low number of measurements. The half-life of ²⁹⁴Ts corresponding to two standard deviations is, based on existing data, 51+76
−32 milliseconds, whereas that of ²⁹³Ts is 22+16
−8 milliseconds; these measurements have overlapping confidence intervals.^[3]
