Naming Copper(II) Oxide: A Chemical Nomenclature Guide

Science >> Science Discoveries > >> Chemistry

The compound CuO is named copper(II) oxide. Here's why:

* Cu represents the element copper.

* O represents the element oxygen.

* (II) indicates the oxidation state of copper, which is +2 in this compound. This is necessary because copper can have multiple oxidation states.

Therefore, the full name is copper(II) oxide.
