Yttrium - ₃₉Y: compounds information

This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of yttrium. For each compound, a formal oxidation number for yttrium 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.

In compounds of yttrium (where known), the most common oxidation numbers of yttrium are: 3.
