Hey mate here is your answer
Symbol: Cu
Atomic Number: 29
Atomic Weight: 63.546
Classification:Transition metal
Phase at Room Temperature: Solid
Density: 8.96 grams per cm cubed
Melting Point: 1084°C, 1984°F
Boiling Point: 2562°C, 4644°F
Discovered by: Known about since ancient times
Copper is the first element in the eleventh column of the periodic table. It is classified as a transition metal. Copper atoms have 29 electrons and 29 protons with 34 neutrons in the most abundant isotope. Copper was one of the first metals to be used by man.
Characteristics and Properties
Under standard conditions copper is a soft orange-colored metal. It is an excellent conductor of electricity and heat. It is also very ductile allowing it to be easily bent and stretched into a wire.
Copper is not a very reactive element, but it will react slowly to air and water. When exposed to air, it will eventually tarnish to a brownish color. If water is also present, it will corrode to form a green carbonate called verdigris. This is what makes the Statue of Liberty green.
