What is the chemical name of Cu2O?

Answer 1

NOT +2

Added:In Cu2O the ion charge is Cu1+, (cuprous oxide, Cu(I) oxide, oxidation state +1) color brownish red (or yellow, depending on how fine the particles are)

In CuO the ion charge is Cu2+, (cuprous oxide, Cu(II) oxide, oxidation state +2) color black

Answer 2

Cu2O is an ionic compound, and the bonds between the cuprous ions and the oxygen ion are ionic. Just about every time you have a metal bonded with a nonmetal (especially if the nonmetal is oxygen, chlorine, or fluorine), it is going to be an ionic compound with ionic bonds.

Answer 3

Cu2O, or cupric oxide is an ionic compound. It is ionic because Cu is a metal, and oxygen is a non metal.

Answer 4

I think you are asking for a common valence value...yes? Copper [Cu+] is generally associated wth a positive valence.

Answer 5

The chemical name of Cu2O is copper(I) oxide.

Answer 6

Copper(I) oxide

Answer 7

Oxygen is nearly always a -2 charge.

Answer 8

It has valency 1.

Answer 9

copper (I) oxide

Answer 10

It is 2-.
