The most positive way to identify copper would be by using a process called spectroscopy, which would leave no doubt as to what it was.
Otherwise, it's a reddish-brown element.
I believe it's color is unique among the elements.
It won't attract a magnet because there's no iron present.
It's both very malleable and extremely ductile, which means it bends and stretches without cracking or breaking.
It may be the most ductile element; it can be stretched into wire that's so thin it's nearly invisible to the naked eye.
It's an excellent conductor of heat.
It oxidizes to a reddish-brown that eventually becomes a light bluish-green.
It melts at 1982.12 degrees Fahrenheit.
The melting point of a metal is good identifying indicator.

If you are identifying pure copper,it's not magnetic unless it is mixed with magnetic
substances as iron.

How is corrosion of copper a chemical change?
Corrosion involve chemical reactions - and these are chemical changes.
What is the chemical reaction in cleaning a penny?
A copper penny builds up a layer of corrosion on its outsides. Probably copper oxide. The cleaning just dissolves the outer corrosion and leaves a new outer layer of copper. CuO + HNO3 --> Cu(NO3)2 + H2O ... the copper nitrate is dissolved in the acid solution and leaves 'clean' copper behind.
What metal is mixed with copper to make brass corrosion resistant alloy?
One word answer: Zinc
How is corrosion measured in the lab?
You can measure it by square inch or by taking the copper and using scientific tools
Why is there a green spot on a potato after electricity has been passed?
Corrosion of copper electrode generates copper salts (which are blue/green) that then diffuse into the flesh of the potato. Don't eat them, copper salts are toxic!!!
What is the word equation for corrosion of copper?
The word equation for the corrosion of copper is: Copper + Oxygen + Water → Copper Oxide.
Can copper turning be used to test how pH affects copper corrosion?
Yes, copper turning can be used as a test specimen to observe the effects of pH on copper corrosion. By subjecting copper turnings to different pH solutions and monitoring the rate of corrosion, one can determine how pH influences the corrosion of copper. This experiment can help in understanding the behavior of copper in different environments.
What makes copper rusty?
corrosion
Why is a gold coin shiny?
it is coated in copper. copper prevent corrosion.
How is corrosion of copper a chemical change?
Corrosion involve chemical reactions - and these are chemical changes.
What is the reaction of benzene cleaning agent on copper containt material?
Corrosion of the copper
How do you store copper?
Copper can be stored in bottles containing water, such that none of the copper is exposed to air, as this can cause the corrosion of copper.
What metal turns green and why?
Copper is a metal that turns green when exposed to air and moisture due to a chemical reaction forming a patina. This patina is a protective layer that forms on the surface of the copper, acting as a barrier against further corrosion.
What is the balanced equation for corrosion of copper?
The balanced equation for the corrosion of copper is: 2Cu(s) + O2(g) + H2O(l) + 2e- -> 2Cu2+(aq) + 2OH-(aq)
What are some examples of corrosion?
Iron and steel rusting is an example of corrosion. Copper pitting or the green patina one sees on copper roofs are also examples of corrosion. Stress Cracking is also considered an example of corrosion.
How good is copper at resisting corrosion?
The corrosion resistance of copper is great! But if the hardness was better and the strength it would be way better than titanium in some cases (not the melting point)!!!
What is a hypothesis for how pH in water Affects Copper Corrosion?
A hypothesis could be that as the pH of water decreases (becomes more acidic), the rate of copper corrosion increases. This is because lower pH levels can increase the availability of hydrogen ions which can accelerate the oxidation of copper. Conversely, at higher pH levels (more basic), the corrosion rate may decrease due to the formation of protective oxide layers on the copper surface.
