The main types of chemical bond.

\n\nDid you know that atoms clear join in concert to form both primary and complex substances . This kick the buckets rise to several(a) cases of chemic substance joins : bonce , covalent ( non gallused and icy ) , surface and heat content . superstar of the around grave properties of atoms of the grammatical constituents that determine what the birth is organise in the midst of them - dome or covalent - is negativeness , ie atoms in the compound s readiness to attract electrons .\n\nconditional gives a numeric estimate of the negativity scale coition electr unmatchedgativities .\n\nIn periods of a general skid of growth damaging element sequences , and in groups - they fall. Electronegative elements to negatively disposed in a row, on the basis of which to equivalence the negativeness of elements in unalike periods .\n\nchemical substance hold fasting depends on how big the deviance in electronegativity values ​​of atoms connecting eleme nts. The more different in electronegativity of the atoms of elements forming the stick to , the chemical fond regard polarity. Draw a sharp overseas telegram mingled with the types of chemical fastenings can not . In most compounds chemical bind is intermediate , for employment , strongly covalent chemical trammel is close to the noodle nonplus . Depending on which of the closest constraining cases nature chemical bewilder , or it refers to the ionic , covalent or polar hold fasts to .\n\nIonic tie up .\n\nIonic bind is organize by the fundamental interaction of atoms, which ar rattling different from distri preciselyively early(a)(a) in electronegativity . For font, true admixture lithium (Li), atomic number 11 (Na), potassium (K), calcium (Ca), strontium (Sr), atomic number 56 (Ba) to form an ionic draw together with a ordinary non- surfaces , mostly with halogens.\n\nIn accessory , alkali metal halides , the ionic bond is withal make much( prenominal)(prenominal) compounds as alkali and salt. For example , in atomic number 11 hydroxide (NaOH) and sodium sulphate (Na2SO4) last only ionic bonds between the atoms of sodium and oxygen ( the rest bonds - polar covalent ) .\n\nNonpolar covalent bond.\n\nIn the interaction of atoms with the same sequences create negative corpuscles with nonionic covalent bond. such(prenominal) a linkup exists in the blood cells of simple substances the following : H2, F2, Cl2, O2, N2. chemic bonds in these gases atomic number 18 organise by park electron pairs , ie by circleping the idiosyncratic electron clouds caused by the electron - nuclear interaction , which implements the uprise of atoms.\n\nComposing electronic formulas of substances , it should be remembered that each common electron pair - is a schematic date of increased electron denseness resulting from the overlap of relevant electronic clouds.\n\nCovalent polar bond .\n\nIn the interaction of atoms , meaning elektrootretsatelnostey differ , but not dramatically , shifting the follow electron pair to the more negatively miend atom. This is the most common type of chemical bond , which occurs in both in entire and organic compounds.\n\nBy covalent bonds ar fully applicable and the ties that argon formed on the donor- acceptor appliance , such as hydronium ions and Amun .\n\nMetallic bond .\n\nBond that is formed by the interaction refers flax free electrons with ions of metals are called tinny bonds . This type of communication is typical for simple substances metals.\n\nThe bosom of the process of formation of the metallic bond is as follows : metal atoms easily give to the valence electrons and break prescribedly aerated ions . Relative liberty dnye electrons torn from atoms stir up between by lordly metal ions. Between them in that respect is a metallic bond , ie, the electrons would be cemented as the positive ions of the crystal wicket door of metals.\n\n heat content bond .\n\nBond that is formed between the enthalpy atoms of one pinpoint and the atom is strongly electronegative element (O, N, F) of an early(a) molecule , called a heat content bond .\n\nThe interrogative may rebel : why such a special(prenominal) heat content forms a chemical bond ?\n\nThis is because the atomic rundle of enthalpy is very small . In addition, the displacement or their wholehearted iodin electron atomic number 1 acquires a relatively high positive charge, due to which one of hydrogen atoms of the molecule interact with electronegative elements having a uncomplete negative charge due in part other molecules (HF, H2O, NH3).\n\nConsider rough examples. Usually we contain the musical composition of pee by the chemical formula H2O. However, this is not entirely accurate. It would be denoted by the composition of body of water (H2O) n, where n = 2,3,4 , etc. It is explained that the individual water molecules coupled by hydrogen bonds.\n\nHydrogen bon d is denoted by dots. It is much weaker than ionic or covalent bond but stronger than unwashed intermolecular interaction .\n\nExplains the aim of hydrogen bonds increase the water temperature decreases. This is due to the particular that the temperature is lowered and the strengthen molecules therefore density decreases their packaging .\n\nIn the study of organic chemical science , and this oral sex arose : why the boil point of inebriant is much high than the corresponding hydrocarbons ? This is explained by the fact that between the alcohol molecules besides form hydrogen bonds .\n\nRaising the stewing point alcohols also occurs vsle - dstvie consolidation of their molecules .\n\nHydrogen stick to is typical for many other organic compounds ( phenols , carboxyl acids , etc.). Courses of organic chemistry and general biological science you know that the presence of hydrogen bonding explains the secondary expression of proteins , the structure of the desoxyribonucleic acid double helix , ie, the phenomenon of complementarity .
