  2. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide reacts with transition metals to give complexes called metal nitrosyls. The most common bonding mode of nitric oxide is the terminal linear type (M−NO). [6] Alternatively, nitric oxide can serve as a one-electron pseudohalide. In such complexes, the M−N−O group is characterized by an angle between 120° and 140°.

    The electron configuration 1 ... Nitric oxide is a heteronuclear molecule that exhibits mixing. The construction of its MO diagram is the same as for the homonuclear ...

  4. Biological functions of nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Biological_functions_of...

    Nitric oxide (nitrogen monoxide) is a molecule and chemical compound with chemical formula of N O. In mammals including humans, nitric oxide is a signaling molecule involved in several physiological and pathological processes. [1] It is a powerful vasodilator with a half-life of a few seconds in the blood.

  5. Octet rule - Wikipedia

    en.wikipedia.org/wiki/Octet_rule

    Octet rule. The bonding in carbon dioxide (CO 2): all atoms are surrounded by 8 electrons, fulfilling the octet rule. The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a ...

  6. Unpaired electron - Wikipedia

    en.wikipedia.org/wiki/Unpaired_electron

    Unpaired electron. Periodic table with elements that have unpaired electrons coloured. In chemistry, an unpaired electron is an electron that occupies an orbital of an atom singly, rather than as part of an electron pair. Each atomic orbital of an atom (specified by the three quantum numbers n, l and m) has a capacity to contain two electrons ...

  7. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    Molecular geometry. Geometry of the water molecule with values for O-H bond length and for H-O-H bond angle between two bonds. Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other ...

  8. Nitric oxide synthase - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide_synthase

    Unlike other enzymes where BH 4 is used as a source of reducing equivalents and is recycled by dihydrobiopterin reductase (EC 1.5.1.33), BH 4 activates heme-bound O 2 by donating a single electron, which is then recaptured to enable nitric oxide release. The first nitric oxide synthase to be identified was found in neuronal tissue (NOS1 or nNOS ...

  9. Transition metal - Wikipedia

    en.wikipedia.org/wiki/Transition_metal

    v. t. e. In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded. The lanthanide and actinide elements (the f-block) are called inner transition metals and are sometimes considered to be ...
