Copper is a metal and exhibits a number of properties that are commonly associated with metals. For example, copper is a solid at room temperature, as are almost all the metals (the exception is mercury). Copper is also a good conductor of electricity, as are other metals. It is because of copper's electrical conductivity that it is very commonly used for electrical wiring at homes, offices, etc. Similar to metals, copper easily donates electrons to become a cation. In fact, copper has two different ionic forms: cuprous and cupric, corresponding to an oxidation state of +1 and +2. Copper also forms ionic compounds with a number of non-metals. An example of such a compound is copper chloride, which is similar to sodium chloride (sodium is another metal).
