Ozone (/ ˈ oʊ z oʊ n /) (or trioxygen) is an inorganic molecule with the chemical formula O 3.It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O

Ozone, O 3 Trihydrogen cation, H 3 +. Homonuclear triatomic molecules contain three of the same kind of atom. That molecule will be an allotrope of that element.. Ozone, O 3 is an example of a triatomic molecule with all atoms the same.
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 are: Atomic oxygen (O 1), a free radical. Singlet oxygen (O * 2), one of two metastable states of molecular oxygen. Tetraoxygen (O 4), another ...
The immune system is thought to use ozonolysis by antibodies organizing 1 O 2 allowing H 2 0 3 to be produced. Traditionally the role of antibodies was thought to be only specifically binding to pathogenic antigens. That antibodies also produced a useful amount of ozone has been debated [2] [3] and was later shown not to be a clear cut result. [4]
The periodic table and law are now a central and indispensable part of modern chemistry. The periodic table continues to evolve with the progress of science. In nature, only elements up to atomic number 94 exist; [a] to go further, it was necessary to synthesize new elements in the laboratory.
Tetraoxygen was first predicted in 1924 by Gilbert N. Lewis, who proposed it as an explanation for the failure of liquid oxygen to obey Curie's law. [1] Though not entirely inaccurate, computer simulations indicate that although there are no stable O 4 molecules in liquid oxygen, O 2 molecules do tend to associate in pairs with antiparallel spins, forming transient O 4 units.

2 produced, but absorbed in oceans & seabed rock; 3) O 2 starts to gas out of the oceans, but is absorbed by land surfaces and formation of ozone layer; 4–5) O 2 sinks filled and the gas accumulates. Free oxygen gas was almost nonexistent in Earth's atmosphere before photosynthetic archaea and bacteria evolved, probably about 3.5 billion ...
