Kumu nonpolar covalent hoopaa. Covalent hoopaa Polar a me ka nonpolar

A nui kūlana ma ka Nine Inch kiʻekiʻe o ka hui ana o ke ao nei Radio ke ano o ke kamailio ana o ka mea kūkulu (particles), ma waena o i huiʻia. I ka lehulehu o ka poe noonoo ole 'ona, o nonmetals i nonpolar covalent loulou type, koe wale no ka mea inert kinoea. Ke hooheheeia ma ka maemae palapala i mau kamailio ana o ka hana i ka mea i hoʻomaopopoʻia socialization o noa electrons i loko o ke aniani puka olu oia.

A pau i ka luna 'waiwai (koe wale no kekahi ke aloha) e Polar covalent Nine Inch paa. Ano a me examples o kēia hui e kūkā mai ma lalo nei. Ma ka manawa, i ke ano o ka'Ātoma e loli ai i ka palapala a polarization.

electronegativity

Nā'ātoma, a oi manaʻoi kona kāna mau 'ōlelo (a, e like me ka makou i ike, ua olelo ikaika mai, papa mai), i ka hiki ia,ʻo a hoomau i ka huina'ine nuʻa, i loko o' ana, ke kahua o Nine Inch paa. Kēia waiwai i kapa electronegativity. Ka papa'āweʻaweʻa kemika Table kona waiwai ulu ma ka manawa, a me ka papa kuhikuhiE hehee wale o na subgroups. Electronegativity waiwai mea i mau mau, a hiki oko, no ka laʻana, hoʻololi i keʻano o ka hybridization, a komo 'ātoma orbitals.

Nine paa, ano a me examples o i i helu 'ia ma lalo, a me ka oi manaʻoi, ka IIeEeAIEUAA a hapa pohupani hale o kēia hui' ana i kekahi o ka paa aku i komo ua wehewehe ia e ka electronegative ano o ka ua hehee ai. Pohupani hale ia lŘlŘ i ka'Ātoma, i mea ikaika.

Nonpolar covalent hoopaa

"Haʻilula" nonpolar covalent linkages alodio - nā nā'ātoma o ka ia ano e hui pu i loko o ka paʻa o ka electrons lākou valence leho. Oia kekahi mau ua kapaia ka māheleʻia no ka mea e pili ana i na aoao elua like me ka paa. He ma socialization huina'ine nuʻa ma ke ano o kekahi mau o electrons, nā'ātoma hoʻoneʻe i loko o ka hale lio ana, no ka piha o ko lakou mau kino mawaho huina'ine pae, a "octet" ( 'ole "lole" i loko o ka hihia o ka poe noonoo ole waiwai o ka hydrogen H _2,ʻo ia wale nō S-orbital, no ka pau 'ana o ka i pono mau electrons) - i ka moku'āina o ka mawaho iliwai, e a pau na nā'ātoma, e like me ka mea hoʻopili like i ka hoʻopiha i ka moku'āina me ka palena iki ikehu.

An kumu o ka non-Polar covalent hoopaa i loko o ka inorganics a, na me ka mea e kani, akā, i loko o ke aloha kemika, no hoi. Kēiaʻano o ka pilina mea, he pono ole ia a pau na mea waiwai - 'ole-ke hooheheeia'ē aʻe ma mua o ka hanohano kinoea, like valence kiʻekiʻe o ka inert kinoea'Ātoma a me ka ua mua octet o electrons pau, a no ia mea, me ka like ka pū'āʻana iho, aole ano no ia, a hiki emi energetically maikaʻi. I ka mea ole-polarity ke aloha mea i loaʻa i loko o kekahi mau 'ole o ka lātoma a me ka mea conditional.

Covalent Polar hoopaa

Kumu nonpolar covalent hoopaa kaupalena 'ia kekahi mau nā lātoma o ka mea waiwai, oiai na hui o dipoles ma i ka huina'ine nuʻa ua hapa' ia 'oni iki i ka oi electronegative hehee ai, - he poi pu oo. Kekahi huihui 'ana o nā'ātoma me kekahi electronegativity waiwai haawi Polar hoopaa. Ma kekahi, ma muli o ia i ke aloha ia mea - he Polar covalent hoopaa. I kekahi manawa, ionic'okanikaʻole oxides mea i Polar, a me ka paʻakai o nāʻakika a me ionic ka ponaʻana predominates type.

E like me ka lōʻihi hihia o ka Polar paa i kekahi manawa ia a me ka ionic type i huiʻia. Inā ka electronegativity o kekahi o na kumu mua mea me ka nui loa mamua o ka mea'ē aʻe, ua pau loa 'oni iki ka huina'ine paʻa mai ka palapala konu ana. No laila, he mea ka mahele i loko o Ion. O ka mea nana kaʻohiʻana i i ka huina'ine mau, ua hoohuliia mai i loko o ka anion, a hookipa mai i ka io ka uku ole, a me ka poho o ka huina'ine - ia iho i loko o ka cation, a lilo ia i mea maikaʻi.

Ano he kumu hoʻohālike o ka'okanikaʻole waiwai me ka covalent hoopaa type 'ole-Polar

Waiwai me ka apolar covalent paa - mea, no ka mea hoike, a pau ka aeaie kinoea nā lātoma: hydrogen (H - H), oxygen (= O), naikokene (i loko o kona lātoma 2 nā'ātoma ua hoʻopili Triple hoopaa (N ≡ N)); ke kinowai a me ka paa waiwai: chlorine (Cl - Cl), fluoro (F - F), bromo (br - br), iodine (I - I). I eiiieaena waiwai oia hoi o nā'ātoma o okoa hehee wale, akā, me ka mea maoli kumukuai o ka electronegativity, no kekahi laʻana, phosphorus hydride - pH _3.

Ke aloha a me ka 'ole-Polar ka paa

Loa ike i nā mea a pau ke aloha mea eiiieaena. Ke ninau mea, pehea la e hiki ai malaila e kekahi nonpolar hoopaa i loko o ka luna 'mea? Ke pane Ua loa na mea, ina he uuku Logical manaʻo. Inā ka electronegativity loina pili oihana mua oko iki, a mai hana i kekahi kūpenu iho ia i manawa i loko o ka hui, ua pilina hiki ke manaʻo like 'ole-Polar. 'O kēia ke kahua me ka kalapona a me ka hydrogen: a pau C - H paa ana i loko o ke aloha ia mea i manaoia e e' ole-Polar.

Kumu nonpolar covalent hoopaa - methane lātoma, ka simplest ke aloha i huiʻia. Ua ninoieo o kekahi kalapona'Ātoma i, e like me kona valence, pili ma ka hookahi paa ana i ka eha hydrogen nā'ātoma. I mea, o ka lātoma mea,ʻaʻole he kūpenu iho ia i, no ka mea, aohe kauoha IIeEeAIEUAA i loko o kekahi mea, a ma ka lilo o ka tetrahedral 'ole. Ka huina'ine nuʻa ua haawi kōā kaulike.

An kumu o ka non-Polar covalent hoopaa mea i oi luna 'ke aloha i huiʻia. Ua Uaʻike ihola i ka lilo o mesomeric loa, i mea, e ku, e huki like huina'ine nuʻa, i koke pio ma ka o carbon kaula. Ke'ī mai, ma ka lātoma hexachloroethane hoopaa C - C nonpolar ma muli o ka hukiʻaʻahu huina'ine nuʻa eono chlorine nā'ātoma.

Other ano o ka paa ana

Ma waho aʻeo ia ka covalent hoopaa, a, incidentally, hiki ke lawe mai i ka pou-acceptorʻano papa hana, eia ionic, mea hao a me ka hydrogen paa. Pōkole ano penultimate mau hōʻike mai iā ia ma luna.

Hydrogen hoopaa - o ka electrostatic intermolecular AaOIeIOUIeXAOAaIN, a hiki'ākoʻakoʻa ina he mea he'Ātoma ma ka lātoma a me kekahi 'ē aʻe o ka hydrogen me unshared huina'ine hui. Kēiaʻano o ka ponaʻana mea nui nawaliwali ma mua o na mea e ae, aka, no ka ai i ka mea ana i ka waiwai o kēia mau paa hiki ke hanaʻia he nui loa, ka poʻea pau me ka nui loa i ka waiwai o ka hui.
