What two properties make oxygen different from copper?
Copper has a much greater mass than oxygen. The other property is the electronic configuration. Oxygen has electrons in the second energy level and is only able to form two bonds. The oxygen molecule is O2 where the two bonds are formed between the two O atoms in the molecule. Copper has a much different electronic configuration which includes other orbitals that are close in energy that are able to be involved in extra bond formation. Copper is a metal and as such forms structures that are strong and have electrons that are delocalized. The delocalized electrons are able to be moved when an electrical potential is applied to the metal. That means that it can carry electrical current. Oxygen has electrons that are localized which means that the oxygen atoms cannot carry current. Cu and O are not even in the same family. I am curious as to why you asked this question.
