What Are the Chemical Properties of Copper?

Copper is a pliable metal with high thermal and electrical conductivity capabilities. It can be identified on the periodic table of elements as Cu and as atomic number 29. Copper and its alloys have been used for thousands of years for various purposes.

How Is Copper Formed?

Copper forms as molten rock with small amounts of copper fluid crystallizes. As the larger rock continues to solidify the fluid rich in copper moves into cracks eventually solidifying as well. Because the copper solidifies later than other minerals within the larger r.
