Helium

Helium compounds

This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of helium. For each compound, a formal oxidation number for helium is given, but the usefulness of this number is limited for p-block elements in particular. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only. The term hydride is used in a generic sense to indicate compounds of the type M_xH_y and not necessarily to indicate that any compounds listed behave chemically as hydrides. In compounds of helium (where known), the most common oxidation numbers of helium are: 0.
