Copper (Cu)
By Sydney Cline
Who discovered it: No one knows who discovered copper because it has been around since prehistoric times.
When it was discovered: Been around since 4,500 B.C. that is the earliest date
Where it was discovered: Copper was discovered in the Middle East, what is present day Egypt and Jordan
How it was discovered: Copper was discovered in a house. There were copper hammers and axes.
Here is the Bohr Model of copper
Egyptians used copper for copper tubing. Copper will not break down for long periods of time. It doesn’t burn or give off any fumes. Copper has antibacterial properties. There is a great abundance of copper in the world. Copper is very durable. It is a ductile metal, has high thermal and conductivity. It’s soft and malleable. Pure copper has a reddish orange color.
- Density: very durable
- Melting Point: 1,984 F
- Atomic Radius: 128pm
- Boiling point: 4,694 F
- Electro Negativity: 1.90(Pauling Scale)
- Ionization energy: 1st 745.5k J. mol -1, 2nd 1957.9k J. mol -1, 3rd 3555k J. mol -1
