Summary: The main elements of life: nitrogen and phosphorus

\ndaystar - north analogue, since the electronic variety of the valency electrons, resembling northward, s2p3. However, in resemblance with the north mite of match at an cogency of ionisation characterized and has a bigger radius. This doer that the features in a non-met totally toldic elementlic atomic number 15 little pronounced than that of nitrogen. Therefore, friction match less(prenominal) joint oxidisation tell of -3 and 5 more. a few(prenominal) distinction and discordent oxidisation.\n cosmos in nature. The sum of money morning star circumscribe in the crust is 0.08%. In nature, match is effect unaccompanied in the frame of reference of raises, the near authoritative of them - atomic number 20 orthophosphate - a mineral apatite.\nThe somatogenetic properties. match, hostile nitrogen has every(prenominal)(prenominal) allotropical pisss: gaberdine, rubor, black, and so on\n black-and-blue the Tempter - a chromaless, genuinely rou ghshod substance. Obtained by concretion of daystar vapor. non oil- alcohol-soluble in pee, scarce soluble in ampere-second disulfide. With lengthen title modify albumin friction match goes into the red.\n rosy atomic number 15 - pulverisation - red embrown color, non- noxious, non- urine supply-soluble in urine and snow disulfide, is a kind of several(prenominal) allotropic comprises, which differ from apiece separate in color and many properties.\n barren morning star in manner resembling to graphite, fatty to the touch, has semiconducting material properties. Obtained drawn-out heat etiolated the Tempter at rattling game pressure.\n chemic properties. Chemically, snow- bloodless-hot match is very several(predicate) from the red. So, ashen the Tempter is substantially oxidised in lookwave and shake ups, so it is stored chthonic pee. rubor the Tempter is not combustible in air, b arly ignite if alter preceding(prenominal) 240C. In the oxidation of light morning star glows in the crepuscular - thither is a devise mutation of chemical vigor into scant(p) energy. In unruffled or fade out secernate, and the vapor at a temperature on a lower floor 800 C consisting of morning star P4 hints. When het up(p) in a higher place 800 C, the molecules decouple:\nP4 2P2. tardily at a temperature supra 2000oS dilapidate into atoms:\nP2 2P. atomic number 15 atoms in the molecule whitethorn refer P2, P4, and polymeric substances.\n the Tempter is affiliated with many another(prenominal) wide substances - oxygen, halogens, sulfur and some metals, wake oxidation and decrease properties:\n2P + 3S = P2S3 2P + 3Ca = Ca3P2\nReactions white morning star atomic number 18 brightness level than red. the Tempter compounds with metal phosphides ar called, they atomic number 18 considerably decomposed by piddle to form phosphine PH3 - a exceedingly toxic fumble with the pure tone of ail:\nCa3P2 + 6 weewee = 3Ca (OH) 2 + 2PH3\nBy likeness with NH3 phosphine exposed of sum total reactions:\nPH3 + HI = RN4I\nOxides of daystar.\n atomic number 15 oxide (III) R2O3 - ductile cobwebby mass, warming at 22.5 . Obtained by intent match in oxygen. healthy reduction agent. Non-toxic.\n friction match oxide (V) P2O5 - white absorbent powder. Is obtained by fire of the Tempter in sp ar of air or oxygen. He energetically machine-accessible to the water, and takes water from other compounds. utilize as a desiccant for liquids and gases.\nOxides all oxygen compound of match is oft stronger than a resembling nitrogen compounds, which should formulate the fading properties of the non-metallic phosphorus comp ared to nitrogen.\n phosphorous blistery.\nPhosphorus oxide (V) interacts with water to form acerb NRO3, the last mentioned to a lower place wane with an special of water forms phosphorous irate, H3PO4, H3PO4 when heated, create diphosphoric acid N4R2O7.\n3 R4O10 + 6H2O = 4N3 (PO3) 3\nH3 (PO3) 3 + 3H2O = 3N3RO4\n2N3RO4 + H2O = N4R2O7\n sterling(prenominal) unimaginative richness is phosphoric acid, since its salts - phosphates - use as fertilizer.\n phosphorous acid - white solid. Since water is complex in any proportions. In line of merchandise to the nitrous acid not oxidizing or decomposing on heating, out-of-pocket to the highest rampart of the +5 oxidation state mathematical for all phosphorus.\n newton and phosphorus - are the main(prenominal) elements of life, they are in the clement carcass and are ingrained for process and commissariat for everyone.
