Ogsajiin «O2 » (Ingiriis : Oxygen) waacuriye kimikeed uu astaankiisuna yahay8 tirada atam kiisuna tahay8 , taasina waxay u dhigantaa inay bu'diisu haysato 8borotoon . Tiradaniyuutaroon -nadu waxay ku xirantahayaysotoob: kan aysotoobka dagani wuxuu leeyahay 8, 9, ama 10 niyuutaroon. Ogsajiinku wuxuu ka tirsan yahay ururka-chalcogan marka la fiirsho tusaha kalgalka, kuwaas oo ahbirma-ahe falgal sarreeya, iyo ogsidheeye u nugul la samaynta ogsaydh curiyaasha iyoiskudhisyada kale. Markii la eegocufka , ogsijiinku waa curiyaha saddex-aad ee ugu badan koonka, goortii laga reebohaydarojiin iyohiiliyam . Beegaalka heerkul iyo cadaadis, labo atam ayaa is-gunta oo sameeya ogsijiin-labaale (dioxygen), kaas oo ahneef (gas) aanmidab 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.
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.
