Ogsajiin

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.
