Nonpolar covalent hoopaa - ka Nine Inch hoopaa i hana ia e ka ia nā'ātoma

Nonpolar covalent hoopaa pili ia i ka hoʻomālamalama mai Nine Inch paa. Ua Ua hanaʻia ka mea, he pono ole huina'ine hui. Aia nō 2 ke ano o ka covalent ahahui i okoa ho okumuʻano papa hana. E hoomanao i kona hoʻonaʻauao, a aʻo hou aku e pili ana i ka mea ka hapanui o ka pili-Polar hoopaa. Ua Ua pinepine i hanaʻia i loko o na mea waiwai - nonmetals, naʻe, hiki ana i ka hui i hanaʻia e ka mea okoa nā'ātoma, a me ka proviso i ka electronegativity waiwai o ka huna like. No ka laʻana, PH3 waiwai EO (P) = EA (H) = 2.2.

E noʻonoʻo pono, e like me ka pili-Polar covalent paa ua hana. Ma ka hydrogen'Ātoma wale kekahi huina'ine, no laila mea i piha kona huina'ine iwi, ka mea nele i 1. Ka AaOIeIOUIeXAOAaIN o ka hydrogen nā'ātoma hoʻomaka e hoʻokokoke kekahi i kekahi aie i na koa o ka attraction o nuclei a me electrons, oiai hapa 'ia' overlapping huina'ine ao. I loko o keia lole ua hanaia, a no ia mau kula haʻahaʻaa (particles). Ma kekahi wahi kahi i ka huina'ine ao overlapped kekahi i kekahi, he mea ka mahuahua huina'ine nuʻa,,ʻo ka'ātoma nuclei, ma laila ka hoʻolako 'ia me ka paa hui lātoma. schematically i kākau Covalent hoopaa nonpolar like penei:

· + H · H - H: H 'ole H - N.

Eia, i ka unpaired huina'ine o ka mea mawaho, ahu iho ua denoted ma kekahi wahi, a me ka huina huina'ine paʻa o nā kiko huina -: aʻulupāʻia.

Mai ka luna ka mea, hiki ke ike i ka wahi o ke ano o ka huina'ine ao ke aupuni 'symmetrically me ka pili ana i na nā'ātoma elua. Ma ka like ano e hana i kekahi pili-Polar covalent hoopaa ma ka hihia o ka poe noonoo ole nā lātoma, waiwai me ka nui helu o electrons.

No keia pilina mea typical no ka loa ole-ke hooheheeia, oe ke hoonoho i ke kumu, e pili ana i kā lākou mau physical waiwai. Waiwai me ka apolar covalent 'ē aʻe paha e paa (silikone, luaipele), kinoea (hydrogen a me ka oxygen) a me ke kinowai (wale bromo). Inā e nānā pono i ka hakakino, ma ssy gaseous a me ke kinowai ai ole-mea hiki ke hooheheeia, ka mea, ua ike ia me ka mahuahua Mr pinepine maoli ka heheʻe, a hoolapalapa ana wela. Me ka paa nonmetals e like me ka mea i kānāwai. Ka mea o ua mau mea waiwai i'ātoma-mea pōaka 'ole i haawi aku no ka ikaika nonpolar covalent hoopaa. Penei, o ka nui o ka helu o ia e pili ana, i ka paʻakikī i ka hui, no kekahi laʻana, daimana a me ka graphite.

Nonpolar 'ē aʻe mea nui i loko o ke ola ana keʻano o ka hanaʻana o nā meaola, e like me ia mea nui ka ikaika a me ka nui i ka pilina paʻa, a me hydrogen ion. I mea e uhai i na ano laulea, holoholona, a kanu pono e hoolilo nui dala o ka ikehu, no laila, i keʻano papa hana o ka make ana o nā'ūhū lawe kaʻeleu loa.

Nonpolar covalent hoopaa - he hoopaa i hana ia e ka ia a me kekahi mau nā'ātoma o kula haʻahaʻaa (particles) o ka luna 'hui ka like aiee o electronegativity. Pela like hoopaa na nā'ātoma e like me ka huina'ine paʻa (lole).
