Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe.

Abstract We have studied the coverage-temperature phase diagram of chemisorbed oxygen on Ni (100) with LEED and AES. We find that the oxygen p (2 × 2) structure undergoes a nearly reversible order- disorder phase transition for coverages between 0.15 and 0.30 monolayer (T c ≈ 560 K for θ = 0.25).

Solid oxygen forms at normal atmospheric pressure at a temperature below 54.36 K (−218.79 °C, −361.82 °F). Solid oxygen O 2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.. Oxygen molecules have attracted attention because of the relationship between the molecular magnetization and crystal ...

Proposed finite temperature phase diagram for solid oxygen at extreme conditions of pressure and temperature. The transition pressures PT, at zero temperature without taking into account the zero-point energy (ZPE), reported by Sun et al.[28] and calculated in the present study, are marked as orange and green circles, respectively.

A U (C,O) single-phase area exists in this diagram. The limit of substitutional solid solution of oxygen atoms for carbon atoms in UC is 12.5 at.%, which means that only 25% of the carbon atoms in UC can be replaced by oxygen atoms. The oxygen-saturated UC phase, U (C 0.75 O 0.25 ), has a lattice parameter of 4.953 ± 0.001 A.

In situ high P-T Raman measurements and optical observations of solid and fluid oxygen up to 1250 K between 8 and 25 GPa reveal the existence of a new molecular phase eta and strikingly unusual behavior of the melting curve. Three triple points were also identified in the P-T domain of the new phase …

Consider the phase diagram for carbon dioxide shown in Figure 5 as another example. The solid-liquid curve exhibits a positive slope, indicating that the melting point for CO 2 increases with pressure as it does for most substances (water being a notable exception as described previously). Notice that the triple point is well above 1 atm, indicating that carbon dioxide cannot exist as a liquid ...

The complete phase diagram of oxygen atoms chemisorbed on Ni(111) has been determined. The two-dimensional system is realized for oxygen coverages of 0.5 monolayers and temperatures 500 K. At higher coverages and temperatures oxygen is incorporated into the bulk. The structure of the oxygen overlayer was determined by low-energy electron diffraction and the coverage was monitored by Auger ...

Oxygen is a gas at standard conditions. However, at low temperature and/or high pressures the gas becomes a liquid or a solid. The oxygen phase diagram shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the oxygen boiling point with changes in pressure.
