Description & History
| Previous considered a colorless gas at 298 K.
Now the team of Berkeley Lab scientists that announced in 1999 the observation of what appeared to be Element 118 -- heaviest undiscovered transuranic element at the time -- has retracted its original paper after several confirmation experiments failed to reproduce the results.
