When copper combines with oxygen to form copper oxide, the charge of the copper ion is?? Yeah
The formula is CuO When Cu +2 combines with O -2 the charges are reduced to lowest term
The name dinitrogen tetroxide tells you that this compound contains? 2 N atoms and 4 O atoms When copper combines with oxygen to form copper(II) oxide, the charge of the copper ion is Cu2+.
Charge? There is no charge on either copper or oxygen in copper(II) oxide, CuO. The copper and oxygen atoms are not ions, and the bonds are more covalent than they are ionic. It is a falacy to assume that all metal-nonmetal bonds are ionic. Nonetheless, you CAN assign oxidation numbers to both copper and oxygen. Copper has an oxidation number of +2 and oxygen has an oxidation number of -2. But remember, oxidation numbers are not ionic charges. There is a great deal of oversimplification when it comes to bonding and introductory chemistry. Bonds are not either ionic or covalent. All bonds lie along a continuum between the characteristics we ascribed to covalent bonds and to Ionic bonds. And while it is possible to have a bond which is 100% covalent, there are no 100% ionic bonds. Even Na-Cl, the most often cited ionic bond, is 30% covalent. =========== Follow up ============ Keep in mind that when people are referring to criss-crossing the charges, they are really referring to the oxidation number,s not a charges, since, as I've mentioned, there are NO copper or oxygen IONS in CuO.
