It reflects red and orange light and absorbs other frequencies in the visible spectrum, due to its band structure, so it as a nice reddish color. For example, pure copper is always a reddish-brown solid (a physical property) and always dissolves in dilute nitric acid to produce a blue solution and a brown gas (a chemical property). If a person keeps in mind the definition of a chemical property, that makes it easier. The misconception is that copper reacts to the water, when really it’s the oxygen in the water that it reacts to. Electrons are the part of the atom with a negative charge that floats around the middle nucleus of positively charged protons and neutral neutrons in a circular motion. This property, in combination with its low thermal expansion, makes it highly useful for wiring applications. And copper is not veryreactive to water (which is one of the reasons why copper makesgreat pipes for use in plumbing). Copper beads have been excavated in northern Iraq and which are more than ten thousand years old and presumably made from native copper, nuggets of which can sometimes be found. Copper also has been used in folk medicine, as it is believed to be healing for those with arthritis. Copper (II) are stable in air than copper(I) compounds. So it has less tendency to get oxidized. This verdigris is not like the rust that forms on iron or other metals, but actually layers, covers, and even protects the copper beneath it. Today, copper is mixed into the paint used to paint the underside of ships. When exposed to the atmosphere, p… Copper is an amazing chemical element that’s been used within society since the ancient days of the Romans. The best example of this is the Statue of Liberty, which was made from pure copper and has since turned into a sea foam greenish color.
