- The Roman Empire was the first to start using cooper.
- They obtained the copper from the ores of cuprite, tenorite, and malachite.
- Matallic gold as color, but soft and bendable.

The Element of Gallium...
Date of Birth
- Proposed to exist by Dmitri Mendeleev in 1871.
- Gallium was discovered by the French chemist Paul-Emile Lecoq de Boisbaudran in 1875.
- Gallium melts near room temperature and has one of the largest liquid ranges of any metals.
- Has a low vapor pressure, even at high temperatures.
- This element has a tendency to super-cool below its freezing point.
- Pure gallium metal has a silvery appearance.
- Gallium is used as a doping material for semiconductors and has been used to produce solid-state items like transistors and light emitting diodes.
- Can produce laser light directly from electricity.
- Gallium Trichloride have been gathered to build the Gallium Neutrino Observatory, an observatory located in Italy built to study particles called neutrinos which are produced inside the sun during the process of nuclear fusion.
- For twenty grams of Gallium it cost 34 dollars.
