Diverging from the conventional Haber-Bosch process, which relies on hydrogen (H_2) to provide both electrons and protons to reduce nitrogen (N_2), homogeneous transition metal complex-catalyzed N_2 reduction reactions (NRR) employ an array of electron and proton donors or even electron donors ...
Number of Protons/Electrons: 7 Isotops: N-13 (half-life 9.97 min.), N-14 (stable), N-15 (stable), N-16 (half-life 7.13 sec.) Crystal Structure: Hexagonal Name Origin: from Greek: nitron (potassium nitrate, KNO3) + genes (former, producer) Nitrogen (N) is an important constituent...
Protons/Electrons: 7Neutrons: 7Shell structure: 2,5Electron configuration: [He]2s22p3Oxidation state:±3,5,4,2Crystal structure: hexagonal As a crucial part of amino and nucleic acids, nitrogen is vital to all forms of life. It was discovered by Daniel Rutherford in 1772. However, ...

protons and electrons for the ORR. In principles, these studies show how precise nitrogen doping allows one to tailor a catalyst׳s structure–property relationship and thus improve its activity for the ORR. However, it is not possible to completely control nitrogen-doping sites in carbon...
Free radicals, reactive oxygen species (ROS) and reactive nitrogen species (RNS) are molecules or molecular fragments containing one or more unpaired electrons in atomic or molecular orbitals, which characterises free radicals with high reactivity (Halliwell and Gutteridge, 1999). ...
Surely this is a great part of our dignity as men, that we can know, and that through us matter can know itself; that beginning with protons and electrons, out of the womb of time and the vastnesses of space, we can begin to understand; that organized as in us, the hydrogen, the ...
protons and electrons in a non-aqueous medium, dinitrogen is reduced to ammonia with an efficiency in electrons of around 65 percent; the remaining electrons are used to make dihydrogen, which is in this context a wasteful and undesirable product. Our catalyst is not great, but it is a ...
Nitrogen, the most common element in our atmosphere, has an atomic number of 7, which means it has 7 protons and 7 electrons. Nitrogen is a diatomic molecule meaning it is more stable when two nitrogen atoms are bonded together rather than being lone atoms....
