So far, the element 108 of the Periodic Table, initiated, has been quite discarded by scientists. When they found him (1984). despite its location in the group, it has not been able to check if it really corresponds.

However, according to a study conducted in collaboration by scientists from several countries, the onset forms a gaseous oxide similar to that of osmo, so it is true that the VIII. is an element of the group and must be located under the osmium.

VIII at very low temperature for research. a new separation and detection technique for group oxides has been used. This technique has been developed by Professor Heino Nitsche of the University of California, in Barkeley. The researchers first fused lighter nucleids and obtained starting atoms, since initiation is not found in nature. Subsequently, the starting atoms obtained were reacted with oxygen and formed gas molecules from the starting oxide.

Finally, the oxide molecules were taken to the detector by a helium jet and the gas molecules were condensed on semiconductor diodes at -20 and -170°C. It was proven that the starting oxide is condensed at a temperature higher than that of osmium oxide, so osmium is more volatile than the initial, so I guess it should be placed under osmium.
