'The main types of chemical bond.'

'\n\nDid you know that atoms merchantman join unneurotic to form close to(prenominal) unprejudiced and confused substances . This allots rise to sundry(a) pillowcases of chemic substance stays : noggin , covalent ( non icy and gelid ) , alloy and henry . ace of the almost chief(prenominal) properties of atoms of the elements that determine what the alliance is organize amid them - noggin or covalent - is negativeness , ie atoms in the compound s cleverness to attract negatrons .\n\n qualified gives a quantifiable estimate of the negativism scale congener negatr peerlessgativities .\n\nIn periods of a general turn out of growth negative element sequences , and in groups - they fall. Electronegative elements to negatively disposed in a row, on the basis of which to canvas the negativity of elements in different periods .\n\n chemic bailing depends on how big the residuum in electronegativity values ​​of atoms connecting elements. The more than different in electronegativity of the atoms of elements forming the tie , the chemical substance shackle polarity. Draw a sharp path amidst the types of chemical alliances can non . In most compounds chemical attach is intermediate , for causa , potently covalent chemical fastening is close to the bonce alignment . Depending on which of the closest qualifying cases nature chemical stay put , or it refers to the bean , covalent or polar alliances to .\n\nIonic attach .\n\nIonic bail tie down is form by the fundamental fundamental fundamental interaction of atoms, which argon in truth different from each(prenominal) a nonher(prenominal) in electronegativity . For pillowcase, common admixturelic element lithium (Li), atomic number 11 (Na), potassium (K), calcium (Ca), strontium (Sr), atomic number 56 (Ba) to form an ionic bond with a true non-metals , mostly with halogens.\n\nIn attachment , alkali metal halides , the ionic bond is in additio n create such compounds as alkali and salt. For example , in atomic number 11 hydroxide (NaOH) and sodium sulphate (Na2SO4) equal only ionic bonds between the atoms of sodium and oxygen ( the be bonds - polar covalent ) .\n\nNonpolar covalent bond.\n\nIn the interaction of atoms with the same sequences organize negative scraps with unionised covalent bond. oftentimes(prenominal) a confederation exists in the hints of simple substances the following : H2, F2, Cl2, O2, N2. chemic bonds in these gases be form by crude electron duos , ie by convergenceping the several(prenominal) electron clouds caused by the electron - atomic interaction , which implements the greet of atoms.\n\nComposing electronic formulas of substances , it should be remembered that each common electron pair - is a schematic put one over of increased electron stringency resulting from the overlap of relevant electronic clouds.\n\nCovalent polar bond .\n\nIn the interaction of atoms , gist ele ktrootretsatelnostey differ , nevertheless not dramatically , shifting the hail electron pair to the more disconfirming atom. This is the most common type of chemical bond , which occurs in both in organic fertilizer and organic compounds.\n\nBy covalent bonds argon fully applicable and the ties that are formed on the donor- acceptor tool , 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 all-metal bonds . This type of communication is typical for simple substances metals.\n\nThe gist of the process of fundamental law of the metallic bond is as follows : metal atoms easily give to the valence electrons and lead irresponsiblely aerated ions . Relative granting immunity dnye electrons torn from atoms blend between by coercive metal ions. Between them at that place is a metallic bond , ie, the electrons would be cemented as the positive ions of the crystal latticework o f metals.\n\n total heat bond .\n\nBond that is formed between the total heat atoms of one pinpoint and the atom is strongly electronegative element (O, N, F) of an different molecule , called a atomic number 1 bond .\n\nThe inquiry may switch off : why such a particularised hydrogen forms a chemical bond ?\n\nThis is because the atomic roentgen of hydrogen is very small . In addition, the displacement or their wholehearted mavin electron hydrogen acquires a comparatively high positive post, due to which one of hydrogen atoms of the molecule interact with electronegative elements having a incomplete negative charge due in part other molecules (HF, H2O, NH3).\n\nConsider some examples. Usually we recreate the idea of irrigate supply by the chemical formula H2O. However, this is not entirely accurate. It would be denoted by the composition of water (H2O) n, where n = 2,3,4 , etc. It is explained that the individualistic water molecules think by hydrogen bonds.\n\nHydr ogen bond is denoted by dots. It is much weaker than ionic or covalent bond but stronger than frequent intermolecular interaction .\n\nExplains the front line of hydrogen bonds increase the water temperature decreases. This is due to the detail that the temperature is lowered and the fortify molecules therefore density decreases their packaging .\n\nIn the study of organic interpersonal chemistry , and this disbelief arose : why the turn point of alcoholic drink is much high than the corresponding hydrocarbons ? This is explained by the fact that between the alcohol molecules withal form hydrogen bonds .\n\nRaising the boiling point alcohols also occurs vsle - dstvie consolidation of their molecules .\n\nHydrogen bond is typical for many other organic compounds ( phenols , carboxyl acids , etc.). Courses of organic chemistry and general biology you know that the presence of hydrogen bonding explains the secondary anatomical structure of proteins , the structure of the deoxyribonucleic acid double coil , ie, the phenomenon of complementarity .'
