The element osmium - basic physical and historical information. Osmium tetroxide (oso 4) it has the highest melting point and the lowest vapor pressure of the platinum elements common uses: microscopy fingerprint detection. Well, initially there would be a glaring gap in the periodic table at atomic number 76 but since many of the elements in the periodic table were discovered precisely because of gaps like that, i doubt if osmium would have escaped being discovered for very long however , if for some reason it wasn.
