It's a compound as the copper and oxygen are chemically bound to each other.
Copper (I) Oxide or Cuprous Oxide
Copper oxide is a compound made up of copper and oxygen atoms. It is not considered a single atom itself, but rather a combination of atoms bonded together.
When copper is heated in oxygen, the compound formed is copper oxide.
When copper is burned in the presence of air, it forms copper oxide. Copper oxide can exist in different forms, such as copper(I) oxide (Cu2O) or copper(II) oxide (CuO), depending on the conditions of the reaction.
Copper is a chemical element. It can be a compound but copper is usually known as a chemical element.
CuO is a compound. It is not a mixture.
Copper (I) Oxide or Cuprous Oxide
copper oxide
CuO is copper (II) oxide, also known as cupric oxide.
No, copper oxide is a compound and has some properties of a semiconductor.
mixture
CuS is known as copper(II) sulphide or Cupric sulphide.
Copper is a element. It is neither compound nor mixture.
The correct chemical formula for copper oxide is Cu2O for copper(I) oxide (cuprous oxide) and CuO for copper(II) oxide (cupric oxide).
Copper(II) oxide is CuO; II is an indication that in this compound copper is bivalent.
Copper oxide is a chemical compound composed of copper and oxygen atoms, not a molecule. It is an inorganic compound that forms when copper reacts with oxygen.
Copper oxide is a compound made up of copper and oxygen atoms. It is not considered a single atom itself, but rather a combination of atoms bonded together.
