Copper - Periodic table

Copper has been used by humans for as many as ten thousand years. Beads made from native copper dating from the eighth millennium BC have been found in Turkey. (1) Crucibles and slags found in Europe suggest that smelting of copper (producing the metal from its ores) took place in the fifth millennium BC.

How Does a Generator Work? | Sciencing

27.11.2018· If a conducting wire standing straight up is moved through the space between the magnets and remains exactly 0.5 meters from each, the motion of the wire is perpendicular to the magnetic field and current is generated along the wire. The magnetic field, wire movement and current direction (and that of the wire) are thus mutually perpendicular.

Aluminum in soil: avoiding aluminum toxicity

Aluminum is one of the most abundant elements on the planet: roughly 7% of the earth’s mass is made up of aluminum. Non-essential for plant growth, available or soluble aluminum can be toxic to plants, whereas other forms—such as aluminosilies and precipitates, or forms of this elemental metal bound up in ligands—are decidedly not phytotoxic.
