The copper on earth was created in a supernova explosion that predated the formation of our solar system (ie before 4600 million years ago).
Copper elsewhere in the universe will have been created at different times in other supernova explosions.
Jewelry, weapons, armors, tools, and various building materials like decorative tiles made of bronze were harder and more durable than their stone and copper predecessors.
It is a key component of the alloy called "bronze", which gave rise to the "bronze age".
Alloying copper with tin to make bronze was first practiced about 4000 years after the discovery of copper smelting
If copper is present, the solution will turnblue...
It is used to extract copper.
Copper its symbol is Cu and its atomic number is 29.

copper (II) oxide
Copper and tin
copper or even more often brass Copper and aluminum are used in house wiring. Aluminum is typically used in the entrance cable and copper for everything past the breaker panel. Aluminum was used for house wiring a few decades ago but it was linked to numerous electrical fires because the connections would weaken over time.
Several used materials in the past: papyrus, parchment, dried clay, copper foils, etc.
Copper is the metal used for plumbing in houses, there are many reasons behind it 1. Copper is the main metal for electrical wiring compare with aluminium. 2. Copper is an excellent conductor of electricity and heat. 3. Copper is resistant to corrosion and very unreactive. Copper is malleable which makes it an ideal material for gas pipes and water pipes. 4. Copper is below hydrogen in the reactivity series and therefore it does not react with water. 5. Copper lead compounds in water are toxic. It was used for plumbing in the past time. For more information visit at: alliedallcityinc.com
They used Seal Blubber and caribou hides and fur
Cu is used for copper as it is an abbreviation of the Latin word for copper, which is Cuprum.
your mom first used copper
It is estimated that there is about 3.5 billions tons of undiscovered copper in the world. Copper has been rising in value for the past several years.
I think the same now, copper.
Iron is more reactive than copper
Iron can be used to get copper from Copper Sulfate because it is more reactive than Copper (higher up in the reactivity series).
Copper-67 is used to treat cancers.
