This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of sodium. For each compound, a formal oxidation number for sodium is given, but the usefulness of this number is limited forp-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.

In compounds of sodium (where known), the most common oxidation numbers of sodium are:1.
