Inerts - mau manaÿo, ka waiwai a me ka noi

i Inert kinoea i kapa aliʻi, kūlana 'i ka papa kuhikuhiE subgroup o ka walu o ka pae ana o ka papa'āweʻaweʻa kemika nenoaiu. No a loaʻa heʻeono wale: helium (He), Neon (Ne), argon ('Ara), xenon (xe), a me ka radon (RN). E ike i ke ano, mua noonoo i ka manaʻo o ka 'oni' ana. Inertness - he nawaliwaliʻa iʻole nā nele o ka hana, e pane koke me nā Nine Inch hehee wale. I ka Nine Inch naoh e lilo hou loulou i loko o kēia mau mea meaʻaneʻane hikiʻole.

Alaila, he inert kinoea - mea he pohihihi keia aliʻi monatomic kinoea me ke kiʻekiʻe 'oni', i mea ku pono i ka energetically hale lio mawaho kiʻekiʻe huina'ine iwi o ka'Ātoma. No ka laʻana, helium i loko o kēia iwi hoolilo mau electrons a me nā aliʻi kinoea - ewalu. Keia wehewehe i ko lakou kino a me ka Nine Inch waiwai. All inert kinoea ma lalo o maʻamau rula kinoea i colorless, odorless a poorly wailana i loko o ka wai. , ua hoʻonuiʻia lākou nā kapuahi e ana wela a me ka mahele heheʻe i ka helu, e like me ka hoomahuahua i ka nui o na nā'ātoma.

A hiki i 1962, nä känaka 'epekema ua paulele ana a pau i ka hanohano kinoea i loa inert. Akā, Junior chemist N. Bartlett ke hooiaio mai i ole ia, e loaa ana i ka mua Nine Inch hui o xenon, he ai-kapaia geksaftoroplatinat xenon. Kēia hui o ka alani paa me ke aniani puka olu oia. A laila i ka helu o nā hui i ua kahaha nui o ka hoʻonui.

Ke prevalence a me ka hoʻonaʻauao ma ka aoao maoli

Ma ka ke ao holoʻokoʻa o ka hanohano kinoea helium o ka loa, he pono ole, a me ka honua ana - argon (ma ka leo ka mea, ninoaaeyao 0,934%). Ma dala uuku loa o inert kinoea i loaʻa i loko o nā pōhaku a me nā kinoea maoli combustible mau mea, a me ka mea hoʻoheheʻe ano hiki ke loaʻa i ka aila a me ka wai.

Ma maoli rula, hanohano kinoea i e ua loaʻa me ka hopena o na nukelea reactions. No ka laʻana, i ke kumu o ka radon e radioactive uranium ai '. Kekahi o kēia mau Nine Inch mai COSMOGENIC kumu.

All inert kinoea a keu aku Rawdon, i ka helu ana o isotopes.

Laau o kēia mau kinoea ua i hoemiia. He wale nō i nā, loa lohi dissipated i loko o interstellar ka lewa.

palapala noi

Inert kinoea i hoʻomano hoʻohana i ka uila wilikî. Argon, ma ka hoomaopopo ana i ka inactivity a me ka haʻahaʻa thermal conductivity, ua hoʻohana 'ia i loko o ka läÿau, me ka naikokene no ka hoopiha ana i ka pila kukui. Argon a me Neon-piha Tube no ka mālamalama kānaka kālepa, a me ka mea, glow uliuli, a me ka Neon -ʻalani-ulaula.

Kekahi Argon ua hoʻohana 'ia i loko o Nine Inch keʻena hoʻokolohua. I ka hana, ka mea, ua loaʻa noi no ka wela lapaʻau o ke hooheheeia hoopuni oxidizable. Ke argon eaaaony i ka aiiay lewa i loko a, e hana i ka kuʻihao a oki pohihihi a me ka 'ole-ferrous metala smelting tungsten, titanium, zirconium. E ka pāʻana hoʻokomo ea nenoai i hoʻohana radioactive isotopes o argon.

Krypton a xenon i ka malie haʻahaʻa thermal conductivity ma mua o Argon, no laila, ua piha oia i na kukui mau nō a me ka hoʻokele waiwai ma mua o ka poe i piha me ka naikokene a argon.

Nā hanu i ka läÿau, o ka helium a me ka oxygen, a hiki me ka nui loa hooloihi i ka lōʻihi like 'ole o ko lākou mau noho ana ma lalo o ka wai, a dramatically ho'ēmi i kā ka eha ole, kena ae la ia e loli ma ka puʻe i ka pii a hiki i ka ili honua.

Wai helium ua hoʻohana 'ia e like me ka refrigerant i ka haʻawinaʻole, mai ke kinoea mahana o ka baila aʻela i -268,9 ° C.

Full 'oni' waiwai o ka helium ia no ka kuʻihao i loko o kona ka lewa, no ka mea? Iecaianoaaiiie o kiʻekiʻe-aku i eliiaʻi, chromatography. A me ka mea hiki i ka ho okumu kiʻekiʻe permeability liu detectors ma ka nakeke haʻahaʻa a me ka kiʻekiʻe puʻe.
