| Herkunft des Namen: | griechisch: oxys and genes, (Säure-bilder) |
| Beschreibung: | Colorless, odorless, tasteless gas; pale blue liquid. Third most abundant element in the universe. It is the most abundant element in the earth's crust, and makes up almost 21% of the atmosphere. |
| Entdeckt von: | Joseph Priestly, Carl Wilhelm Scheele |
| Jahr: | 1774 |
| Ort: | England/Schweden |
| Quelle(n): | Obtained primarily from liquid air by fractional distillation. Small amounts are made in the laboratory by electrolysis of water or heating potassium chlorate (KClO3) with manganese dioxide (MnO2) catalyst. |
| Verwendung(en): | Gebraucht für Stahlherstellung, schweissen. Natürlich vorkommendes Ozon (O3) in der oberen Atmosphäre schützt die Erde vor UV-Strahlung. |
