Mekala 'åkilikai ke hooheheeia

Mekala 'åkilikai ke hooheheeia - francium, cesium, rubidium, potasiuma, paʻakai, likiuma - no laila, i kapaʻia no ka mea, o ka mea nui, e hoike ana i ke ano o ka mekala' åkilikai ma naoh me ka wai. Aie i ka hiki kiʻekiʻe, e pane koke mau manawa e hehee wale e waiho waho ma lalo o ka papa o ka mea pōhaku aila paha kerosene. Ka K'lauea o kēia hui ua noʻonoʻo francium (mea radioactive).

Mekala 'åkilikai ke hooheheeia - waiwai palupalu, silvery waihoʻoluʻu. Lākou freshly kua ili mai i ke ano alohilohi. i hehee mekala 'åkilikai i eliiaʻi a me ka mai hehe ma haʻahaʻa mahana, i kiʻekiʻe thermal a me ka uila conductivity. Lakou no hoi i ka haʻahaʻa nuʻa.

Nine waiwai o ka mekala 'åkilikai ke hooheheeia

Waiwai i ikaika hoemi hope, na hui ho'āʻo keʻano o ka'okesaside (hanana) +1. Me ka mea ulu i loko o'ātoma kaupaona mekala 'åkilikai ke hooheheeia, a māhuahua hoemi hiki. Kokoke a pau o ka hui, ua wailana i loko o ka wai, ka mea i ionic ma ka ano.

Me ka lōpū paio hahana maoli nō mekala 'åkilikai ke hooheheeia ignite ma ka lewa. Ma ka huipūʻana me ka hydrogen kuahene paakai-e like ka waiwai hydrides. 'ā huahana mea nō kāu peroxides.

Mekala 'åkilikai metala oxides i yellow puaʻa hiwa (oxides o rubidium a me ka potasiuma), keʻokeʻo (oxides o ka paʻakai , a likiuma) a me ka alani (Cesium'okesaside) waihoʻoluʻu. Mau oxides i hiki ke reacting me ka wai, nāʻakika, oxygen,ʻakika a me amphoteric oxides. Mau kumu ano e hoʻomaopop 'ana i nā mea a pau o ia a i ka hai külana.

peroxides o ka mekala 'åkilikai ke hooheheeia - he lepo lā yellow-keʻokeʻo waihoʻoluʻu. Ka mea, e hiki no reacting me ke kalapona'okikene lua a me ka kalapona monoxide kinoea, nāʻakika, nonmetals, wai.

mekala 'åkilikai metala hydroxides i wailana i loko o ka wai, keʻokeʻo puaʻa hiwa. Ma kēia mau hui i hōʻike (ao alohilohi i lawa) walaʻauʻana waiwai alkalis. Likiuma kumu i Manuela mana a me ka degere o ka solubility i loko o ka wai, piʻi pū. Hydroxides noonoo ikaika lawa electrolytes. Ka mea, pane koke me ka paʻakai, amphoteric hydroxides a me oxides, kekahi ole-ke hooheheeia, ʻakika oxides. Ina i huiia me ka likiuma koena ho'āʻo thermal kumupaʻa. Calcining likiuma hydroxide o kona decomposition i loko o ka wai, a me ka'okesaside. Mai la i huiʻia i loaa mai ma ka mea o ka electrolysis o koʻana koko koloriside pāʻoihana o ka helu o metabolic reactions. hoomakaukau no hoi Hydroxides ma reacting eiiiiiaiou (a oxides) a me ka wai.

Kokoke i ka paʻakai i ho'ākāka 'ia i eliiaʻi (koe wale no ka kekahi likiuma paʻakai) i wailana i loko o ka wai ola. I hanaʻia ma ka nawaliwali nāʻakika, Saline pāʻoihana i ka naoh meakino (kona'ākilikai) ma muli o ka hydrolysis o ka hana paakai i ikaika nāʻakika i ole hydrolyzed. Common paʻakai i pohaku (paʻakai) paakai, he silicate lina (ka wai aniani), potasiuma nitrate, bertoletova paakai, potasiuma permanganate, omole soda, soda lehu, a me na mea e ae.

A pau o ka mekala 'åkilikai i huiʻia i ka hiki ke hoʻololi i ka waihoʻoluʻu o ka lapalapa ahi. Ua Ua hoʻohana 'ia i loko o Nine Inch Ka Ikepili. Penei, ulaula iaʻi lakou lapalapa carmine me likiuma Ion, ma ka lila - potasiuma Ion ma melemele - paʻakai whitish a pink - rubidium, lila-ula - cesium.

Aie i ka mea i pau'ākilikai aeee i ka loa mana hoemi konohiki, ka mea hiki ke loaa i ka paʻakai i hoʻoheheʻeʻia ma ka electrolysis.

E ho ohana i ka mekala 'åkilikai metala

e hoʻohana 'ia nā kumu i loko o kekahi spheres o kanaka haʻawina. No ka laʻana, ua hoʻohana 'ia i loko o cesium photoelectric keena. Ka hanau ana oka a ua hoʻohana 'ia e like me ka hōʻeleu likiuma. Paʻakai mea i loaʻa i loko o ke kinoea-hookuuia kukui, nukelea reactors like me ka coolant. I ka noiʻi ha awina Ua hoʻohana rubidium.
