Ogsajiin «O₂» (Ingiriis: Oxygen) waa curiye kimikeed uu astaankiisuna yahay 8 tirada atam kiisuna tahay 8, taasina waxay u dhigantaa inay bu'diisu haysato 8 borotoon. Tirada niyuutaroon-nadu waxay ku xirantahay aysotoob: kan aysotoobka dagani wuxuu leeyahay 8, 9, ama 10 niyuutaroon. Ogsajiinku wuxuu ka tirsan yahay ururka-chalcogan marka la fiirsho tusaha kalgalka, kuwaas oo ah birma-ahe falgal sarreeya, iyo ogsidheeye u nugul la samaynta ogsaydh curiyaasha iyo iskudhisyada kale. Markii la eego cufka, ogsijiinku waa curiyaha saddex-aad ee ugu badan koonka, goortii laga reebo haydarojiin iyo hiiliyam. Beegaalka heerkul iyo cadaadis, labo atam ayaa is-gunta oo sameeya ogsijiin-labaale (dioxygen), kaas oo ah neef (gas) aan midab iyo ur toonna lahayn oo la yiraahdo neef laba atamle (diatomic gas) oo leh naaneysta (formula) O₂. Ogsijiin- labo atamle (diatomic oxygen) wuxuu ka kooban yahay 20.8% ee gibilka dhulka. Madaama ay iskudhisyadiisa ay ka midyihiin ogsiidhyo, oogada dhulka badhkeed ayaa ka sameysan curiyaha.

Taariikhda Ogsajiinta

Tan iyo xilligii Dhagaxa, gubashada waxay ahayd mid ka mid ah dhacdooyinka ugu faa'iidada badan aadanaha taariikhda oo dhan, isla markaana ka mid ah kuwa ugu qarsoon. Faylasuufyo iyo saynisyahano badan, laga soo bilaabo Xilligii Giriiga iyo ka dib, Sida Fiilo ee Bisantiinyiintu, ilaa khubaro iyo kiimikooyin Muslimiin ah oo qarniyadii dhexe ahaa, ayaa isku dayay inay sharaxaan dhacdadan, iyagoo bixinaya fasiraado kala duwan. Dabka waxaa loo arkay mid ka mid ah afar walxood oo dhaqameed ah, sida laga soo xigtay fahamka baahsan ee caalamka waqtigaas, oo ka kooban Caalamka.

Isticmaalka Ogsajiinta

Oxygen

Oxygen Waxa uu ka mid yahay qaybaha ugu muhiimsan ee kimikada waxaana loo soo gaabiyaa xarafka ah "O" Atam kiisuna waa 8 waana gaaska aduunka ugu badan.
