  2. Nitrogen difluoride - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_difluoride

    Nitrogen difluoride is formed during the function of a xenon monofluoride excimer laser. Nitrogen trifluoride is the halide carrier gas, which releases fluoride ions when impacted by electrons: [1] NF 3 + e − → NF 2 + F −. The free fluoride ion goes on to react with xenon cations. [1] Nitrogen difluoride can be consumed further to yield ...

  3. Noble gas - Wikipedia

    en.wikipedia.org/wiki/Noble_gas

    Noble gas is translated from the German noun Edelgas, first used in 1900 by Hugo Erdmann [ 5 ] to indicate their extremely low level of reactivity. The name makes an analogy to the term " noble metals ", which also have low reactivity. The noble gases have also been referred to as inert gases, but this label is deprecated as many noble gas ...

  4. Properties of nonmetals (and metalloids) by group - Wikipedia

    en.wikipedia.org/wiki/Properties_of_nonmetals...

    Krypton can be reacted with fluorine to form the difluoride, KrF 2. The reaction of KrF 2 with B(OTeF 5) 3 produces an unstable compound, Kr(OTeF 5) 2, that contains a krypton-oxygen bond. Pressurized xenon gas encapsulated in an acrylic cube. Xenon has a density of 5.894 × 10 −3 g/cm 3, liquifies at −161.4 °C, and solidifies at −165. ...

  5. Fluorine compounds - Wikipedia

    en.wikipedia.org/wiki/Fluorine_compounds

    Fluorine's chemistry includes inorganic compounds formed with hydrogen, metals, nonmetals, and even noble gases; as well as a diverse set of organic compounds. [note 1] For many elements (but not all) the highest known oxidation state can be achieved in a fluoride. For some elements this is achieved exclusively in a fluoride, for others ...

  6. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element bond to form N 2, a colorless and odorless diatomic gas.

  7. Nitrogen compounds - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_compounds

    The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.

  8. Difluoride - Wikipedia

    en.wikipedia.org/wiki/Difluoride

    Difluoride. Difluorides are chemical compounds with two fluorine atoms per molecule (or per formula unit). Metal difluorides are all ionic. Despite being highly iconic, the alkaline earth metal difluorides generally have extremely high lattice stability and are thus insoluble in water :D. The exception is beryllium difluoride.

  9. Octet rule - Wikipedia

    en.wikipedia.org/wiki/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 noble gas. The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens; although more generally the ...
