The Swedish company had been planning to make a record attempt in the next few days, but we believe the plan has now been put on ice.*. Porscheâs 918 Spyder may very well hold the production-car lap record forever. Of course, thereâs a justifiable view that Nordschleife record claims have been running out of control in the last few years, especially when it comes to the number of subcategories that manufacturers seem determined to claim as their own.
There are several known allotropes of oxygen. The most familiar is molecular oxygen (O 2), present at significant levels in Earth's atmosphere and also known as dioxygen or triplet oxygen.Another is the highly reactive ozone (O 3). Others include: 1  Atomic oxygen (O 1, a free radical).2  Singlet oxygen (O 2 *), either of two metastable states of molecular oxygen.ee also: Dioxygen in biological reactions. The common allotrope of elemental oxygen on Earth, O 2, is generally known as oxygen, but may be called dioxygen or molecular oxygen to distinguish it from the element itself.
Oxygen is an element with the chemical symbol O and atomic number 8. Oxygen is a very reactive element that easily forms compounds such as oxides. Under standard temperature and pressure conditions two oxygen atoms join to form dioxygen (O 2), a colorless, tasteless and odorless gas.Oxygen is essential to human life, it is found in the air we breathe and the water we drink (H 2 0).zone (O 3) is an allotrope (different form) of oxygen that combines three oxygen atoms together. While ground level ozone is an air pollutant, the ozone layer in the Earthâs upper atmosphere provides protection from the suns harmful rays by filtering UV light.
