∙ 13y agoCu2O 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.

∙ 9y agoCu2O, or cupric oxide is an ionic compound. It is ionic because Cu is a metal, and oxygen is a non metal.

Chemical Name of CU2O?
cuprous oxide :)
What is the chemical name of the product formed when copper reacts with a gas in air?
When the product is with oxygen it will be copper oxide CuO. If it is with nitrogen it is copper nitrate.
What is the Chemical equation for Benedict's test?
R-CHO + 2Cu2+ + 4OH- ----------> R-COOH + Cu2O + 2H2O where R is the group attached to the aldehyde (CHO)
What type of chemical is copper oxide?
Do you mean carbon dioxide(carbon IV oxide - CO2) or carbon monoxide CO
Chemical formula of cuprous oxalate?
Cu2O. Cuprous is Cu+, cupric is Cu2+. Those are old-school names. Copper(I) oxide is a better name.
Chemical Name of CU2O?
cuprous oxide :)

The chemical formula is Cu2O
What is the name of the compound formed from the chemical reaction copper and oxygen?
Copper (II) oxide or cupric oxide: CuO.Copper (I) oxide or cuprous oxide: Cu2O.
What Is the name of the compound formed form the chemical reaction between copper and oxygen?
Copper (II) oxide or cupric oxide: CuO.Copper (I) oxide or cuprous oxide: Cu2O.
Name a compound formed from the chemical reaction between copper and oxygen.?
Cuprous oxide, or copper (I) oxide, Cu2O, is a red powder.Cupric oxide, or copper (II) oxide, CuO, is a black powder.
What is the compound Cu20?
Cu2O, where the 2 should be a subscript, is copper(I) oxide or cuprous oxide to give it its old name. It is found naturally as the ore cuprite. It is a red-brown powder, whereas the copper(II) oxide we see when copper is heated is black.
