how do i oxidize copper?

Bury copper in white vinegar. White vinegar can produce a green or blue patina on copper, but requires another material to hold the moisture close to the metal. Let the copper soak in a mixture of white vinegar and salt, or bury it in sawdust or even crushed potato chips, then soak the mixture with vinegar.

To get the greatest health benefits, try to combine water from your copper water bottle with lemon slices or lemon juice in a cup. Copper can react with certain acids, including citric acid found in lemons, so it's best to only use water in your copper water bottle.

Copper has two electrons in the innermost shell, eight in the next shell, eighteen in the third shell, and one in the fourth shell. This means that the first three shells each have as many electrons as they can hold, and the fourth shell has one lonely electron. (The fourth shell can hold up to 32 electrons.)

Since brass doesn't react with either the copper or the zinc, one method is to make sure you have a threaded female end on both the copper and the steel pipes, and then connect the two by simply inserting a short threaded brass nipple between them.

As you can see, copper is above silver in the reactivity series, meaning it is more reactive than silver, and will replace the silver in the silver nitrate compound.

Hydrogen peroxide can also be used to oxidise iron, manganese and sulphur, which can then be removed with filtration. The US Environmental Protection Agency (EPA) guidelines recommend 25 to 50 ppm of residual H2O2 in drinking water.

In order to write the Copper electron configuration we first need to know the number of electrons for the Cu atom (there are 29 electrons). Once we have the configuration for Cu, the ions are simple. When we write the configuration we'll put all 29 electrons in orbitals around the nucleus of the Copper atom.

Atoms, ions, and molecules that have an unusually large affinity for electrons tend to be good oxidizing agents. Elemental fluorine, for example, is the strongest common oxidizing agent. F2 is such a good oxidizing agent that metals, quartz, asbestos, and even water burst into flame in its presence.

Oxidation is the reaction of a substance with oxygen. This is the process that causes rust. When iron in rocks reacts with oxygen, it forms iron oxide, which weakens the rock. Carbonation is the mixing of water with carbon dioxide to make carbonic acid.

Electrolysis is commonly used to extract these metals and requires a lot of electric current (energy) to reduce them to extract the metal. Less reactive metals, such as iron, form less stable oxides and other compounds.
