Is only slightly magnetic. Not magnetic enough to interact with regular magnets. Electronegativity is 1.90 in Pauling units. Atomic size is 128pm. Electron affinity is 118.4 kJ/mol. Metallic
Chemical properties
Copper does not react with oxygen. It reacts with water though. Copper will melt, but it won't burn to well. Since it's a metal it's flammability is near zero
Copper is not soluble in water
Oxidation States: +2, +1

USES
- Coins
- Wire
- Jewelry
- Water pipes
- Alloys
Large amounts of copper ore deposits are found in the U.S., Chile, Zambia, Zaire, Peru, and Canada. Found in soil, rocks, and at the bottom of ocean.Copper ore is mined. Then copper is extracted from the ore. Damages the environment
