One of these elements forms a Rollin film that exhibits the fountain effect at low temperatures.
Lee, Osheroff, and Richardson hypothesized that the properties of an isotope of an element in this group were due to fermions forming Cooper pairs. One of these elements forms a Rollin film that exhibits the fountain effect at low temperatures. An element's abbreviated (*) electron configuration puts the chemical symbol of the last preceding member of this group in square brackets. Neil Bartlett discovered that another one of these elements could form a compound with platinum and six fluorine atoms despite this group's unreactivity. For ten points, name this group of elements which have full valence electron shells and include helium and xenon.
