  2. Allotropes of oxygen - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_oxygen

    Singlet oxygen is the common name used for the two metastable states of molecular oxygen (O 2) with higher energy than the ground state triplet oxygen. Because of the differences in their electron shells, singlet oxygen has different chemical and physical properties than triplet oxygen, including absorbing and emitting light at different ...

    en.wikipedia.org/wiki/Homonuclear_molecule

    Homonuclear diatomic molecules include hydrogen (H 2), oxygen (O 2), nitrogen (N 2) and all of the halogens. Ozone (O 3) is a common triatomic homonuclear molecule. Homonuclear tetratomic molecules include arsenic (As 4) and phosphorus (P 4). Allotropes are different chemical forms of the same element (not containing any other element). In that ...

    en.wikipedia.org/wiki/Octaoxygen

    Octaoxygen, also known as ε-oxygen or red oxygen, is an allotrope of oxygen consisting of eight oxygen atoms. This allotrope forms at room temperature at pressures between 10 and 96 GPa. This allotrope forms at room temperature at pressures between 10 and 96 GPa.

  7. Allotropy - Wikipedia

    en.wikipedia.org/wiki/Allotropy

    Diamond and graphite are two allotropes of carbon: pure forms of the same element that differ in crystalline structure.. Allotropy or allotropism (from Ancient Greek ἄλλος (allos) 'other' and τρόπος (tropos) 'manner, form') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.

  8. Hemocyanin - Wikipedia

    en.wikipedia.org/wiki/Hemocyanin

    Most hemocyanins bind with oxygen non-cooperatively and are roughly one-fourth as efficient as hemoglobin at transporting oxygen per amount of blood. Hemoglobin binds oxygen cooperatively due to steric conformation changes in the protein complex , which increases hemoglobin's affinity for oxygen when partially oxygenated.

  9. Ozone - Wikipedia

    en.wikipedia.org/wiki/Ozone

    Ozone, along with reactive forms of oxygen such as superoxide, singlet oxygen, hydrogen peroxide, and hypochlorite ions, is produced by white blood cells and other biological systems (such as the roots of marigolds) as a means of destroying foreign bodies. Ozone reacts directly with organic double bonds.
