While the properties of each of these seven nonmetals are thoroughly documented, their collectively shared physical and chemical properties have been regarded as being too diverse to bother. Consequently, they have sometimes been referred to as, for example, [mere] "nonmetals"; "miscellaneous nonmetals"; "orphan nonmetals"; or "other nonmetals", as if consigned to a classification science junkyard or "too hard" basket. 11 As noted, the net result of this disaggregated approach was expressed by … "The marvellous variety and infinite subtlety of the non-metallic elements, their compounds, structures and reactions, is not sufficiently acknowledged in the current teaching of chemistry." …and it is still relevant in the context of the unclassified nonmetals (and the metalloids).
