Copper 65 is an isotope of copper. It is a stable non-radioactive metal that is naturally occurring and possesses a large range of applications. Some of the important uses include plumbing, electric wiring, and construction materials. In addition to its applications in the environment, copper has many other uses, including in jewelry, cooking utensils, and electrodes.

Cu is a naturally abundant element in the earth’s crust. However, its toxicity can be acquired, and it can be released into the environment in various natural events. One example is the release of copper ions from intrauterine contraceptive devices, which can be toxic to embryos. Another example is the use of copper in electroplated protective coatings.

Copper is a ductile metal that is slightly soluble in hydrochloric acid. When heated, it forms a red cuprous form. Several enzymes require copper to perform their function. Various ligands also form complexes with the metal.

A variety of studies have investigated the effects of copper isotopes on human body kinetics. For instance, in gastrointestinal diseases, copper can be absorbed into the body through the bile. It is also used in cancer diagnosis and treatment.

The Copper-65 stable isotope has been suggested to be a precursor for the production of the radioactive copper isotope, Cu-64. But, there is no evidence to support this.

As the atomic mass of the isotopes varies, there is a certain degree of uncertainty associated with the atomic number. This uncertainty is expressed in the nuclide notation, which shows information about the isotope in a concise form.
