Ndechipi polar covalent chisungo

Polar covalent chisungo - ndiko chimiro chimwe makemikari ukama pakati maatomu kwemashoko panopinda mamorekuru aumba. Kana shoko "kukurukurirana" matambudziko nokunzwisisa hakuitiki, okuti "covalent" uye "Polar" untrained munhu zvisingazivikanwe (Chokwadi, chero bedzi zvezvaidzidziswa wekemisitiri inokanganikwa).

Saka, shoko rokuti "covalent" rinobva "Ko" uye "-valenta", rinoreva munhu achitaura nesimba. Zvechokwadi, ndiwo simba anokwanisa nokubatanidza maatomu maviri ari Morekuru, reconfiguring kwavo Erekitironi anoshongwa mune rimwe marongerwo. Sezvo vose cores vakaenzana, kutenderera maerekitironi vazadze kwete chete "kwokunze" divi, asiwo musiyano pakati maatomu. Tinogona kutaura kuti iye covalent chisungo. Saka yakadaro hunyambiri gadziriro chaitwa kupedzwa ari yemagetsi configuration, sezvo vaitarisira vatakuri dzinopindirana nevamwe kuwirirana maatomu. Ona kuti peya maerekitironi zvokurimisa ichi mhando yokukurukurirana.

Chimwe pachake iyoyi anganzi Ion mhando kubatana. Sezvo Ion aumbwa apo atomu anorasikirwa ane Erekitironi, zvikaitika kana akaipa mutariri vatakuri Exchange, iyo maitire nokuda maatomu dzakasiyana zvinhu (somuenzaniso, fluorine, uye yavaibvisa).

Polar covalent chisungo - chinhu zvenguva nzira. Izvi mhando chakafanana "covalent wakachena" rinoumbwa samolecular orbital (yesangano kutenderera), uye kubva Ion mairi haasaruri "Tug" mutariri vatakuri. Vaviri ari zvava mumwe maatomu, asi kwete zvakakwana kusiya imwe mapazi. Muenzaniso umo mutambo ane polar covalent chisungo - mvura Morekuru. Finished goko akasikwa tichibatanidza rimwe okisijeni atomu uye vaviri rehydrogen. Zvisinei, sezvo okisijeni ane zvimwe raidudzwa kugona kukwezva maerekitironi, nemhute dzavo inofamba ichienda musimboti ndiye "O". Sezvineiwo, hakusi maatomu zvakafanira vanoumba peya maerekitironi kunogona vaviri, vatatu, etc. Polar covalent chisungo pave mutariri Kuparadzirwa gadziriro (zvishomanana) uye, sezvo zvakaita kuti polarity. Pane ari nezvatinovavarira mamorekuru dzesango mitsetse. Ungati kuti nemhaka kuparadzirwa ichi chinovapo pachangu samolecular dipole. nguva yaro (mü) uye zvinowanisa yemagetsi munda zvikuru. Pane zvinhu zvinoverengeka zvaifanira kushandiswa pakuverenga ari dipole nguva (zvikurukuru, nezvibereko zvomunda daro vebasa), vanogona exchange kukosha kunorondedzerwa polarity yacho Morekuru.

Mune mamwe mazwi, munhu polar covalent chisungo inogona inoumbwa maatomu, izvo kunyange vakasiyana electronegativity, asi kwete zvakakwana kuti pave Ionic chisungo. Regai titsanangure chii electronegativity. Iri izwi rinoreva mano imwe atomu kukwezva kuna paro kuumbwa (-th) peya kunaka vebasa vatakuri. Zviri pachena, maererano nomurayiro kuchengetedza simba, zvikuru mabhomba pazvisungo, kashoma zvavo kureba. Kazhinji, covalent polar chisungo hunhu maatomu, zvemakemikari maitiro akafanana. It kunoratidzwa ne spatial nemunhu. Izvi zvinoita kwete chete paumbwe mamorekuru, asiwo sekristaro yekamuri iyo maatomu vanosarudzirwa mune geometrically nenhevedzano.

Kubvira kubatana, chokwadi, iri superposition zviviri (kana kupfuura) kubva Erekitironi makore enzvimbo maatomu siyana, simba rayo kunonyanya sei zvakasimba kuifukidza kunoitika. Zviri nyore kunzwisisa kuti paakasika mbiri, internuclear gwanza kukosha Erekitironi arambe achirema inowedzerawo.
