Nonpolar covalent ibhondi - iqhina yemichiza akhiwa atom efanayo

Nonpolar covalent bond libhekisela elula iibhondi imichiza. Oku akhiwa ngababini electron eqhelekileyo. Kukho 2 iintlobo emibutho covalent ezi ndlela ezahlukeneyo ukubunjwa. Cinga imfundo yakhe kwaye ufunde ngakumbi malunga nokuba yintoni na ubukhulu becala le a non-ezibandayo. Idla kwasekwa izinto ezilula - nonmetals, Noko ke, kwenzeka imichiza lisekwa athom carbon ezahlukeneyo, phantsi kwelungiselelo elithi ixabiso electronegativity ye amasuntswana nezakhiwo iyalingana. Umzekelo, PH3 kweziyobisi EO (P) = EA (H) = 2.2.

Cinga, njengoko kwasekwa non-polar covalent bond. Xa i-atom hydrogen electron omnye kuphela, ngoko iqokobhe layo electron ayikho epheleleyo, lingabi nokuba 1. impefumlelwano athom Iperoksayidi aqale ukusondela nomunye ngenxa imikhosi yomtsalane of nuclei kunye elektroni, lo gama amafu electron ngokuyinxenye zidlulela. Ngeli doublet ezikhandelwa, lalo amasuntswana ezimbini sabaqalayo. Kwindawo apho amafu electron kwakudibana enye kwenye, kukho electron mninzi ukwanda, etsala eziba atomic, ngaloo ndlela kubonelelwa ngazo zinemoletyhule compound esiqinileyo. Covalent bond nonpolar ngokwalo esibhaliweyo ngolu hlobo lulandelayo:

· + H · H - H: H okanye H - N.

Apha, electron unpaired ye umaleko lwangaphandle luchazwa ngenqaku elinye, kwaye lilonke electron iperi amachaphaza amabini -: okanye dash.

Ukusukela ingentla kuyabonakala ukuba indawo ukudibana amafu electron ibekwe symmetrically mayela atom ezimbini. Ngendlela efanayo ukuba ibe non-polar covalent iqhina xa molekyuli ezilula, izinto ukuba inani elikhulu electron.

Ekubeni lo buhlobo ekuso kuninzi non-ngesinyithi, uyakwazi wamisela umzekelo, enxulumene zomzimba iipropati. Substances nombutho covalent apolar inokuba eqinileyo (lesilicon, isalfure), iigesi (hydrogen neoksijini) kunye ulwelo (kuphela bromo). Ukuba ujonga ngeliso e ma molecule ssy sukube kunye ulwelo non-metal, kuba wabona ukuba ukwandisa uMnu rhoqo kwandisa ukunyibilika kwaye abilayo lobushushu. Nge nonmetals eqinileyo efana ayenzeki. Eyona nto kukuba ezi izinto ezilula kufuneka isakhiwo atomic-crystalline leyo anika amandla nonpolar covalent bond. Ngoko ke, lo elikhulu inani uqhagamshelwano olunjalo, exhaleni ezimbaxa, umzekelo, idayimani kunye mifanekiso.

umbutho Nonpolar ibalulekile kwiinkqubo zobomi eziphilayo, njengoko yomelele kakhulu kwaye ezinzileyo ngakumbi, hydrogen ion. Ukuze ndiwaphule ezifana, isilwanyana okanye isityalo kuyimfuneko ukuchitha imali eninzi yamandla, ngoko ke indlela wentshabalalo enqanda kokuba uthathe inxaxheba.

Nonpolar covalent bond - ibhondi akhiwa atom efanayo okanye ezahlukeneyo amasuntswana nezakhiwo ezimbaxa nezintsonkothileyo ukuba amaxabiso ezilinganayo electronegativity. Kulo mzekelo ubambe ngokulinganayo le atom eqhelekileyo isibini electron (doublet).
