Malunga Oxygen
I-Oxygen iyi-nonmetal enamandla kakhulu futhi iyingxenye eminingi emhlaba. Ifaka ama-oxides ngezinto eziningi. I-Oxygen ibalulekile ekuphefumuleni kweselula nokudlidliza. I-ozone layer ivikela impilo emhlabeni kusuka emisebeni ye-ultraviolet.
Izisebenziso
Ukwenza insimbi, igesi yokuphefumula yezokwelapha, ukubopha nokugoqa, ukwelashwa kwamanzi, i-rocket propellant, kanye nokukhiqizwa kwe-chemical.
Iqiniso elijabulisayo
I-oxygen i-paramagnetic -- i-oxygen ephuzi iluhlaza okwesibhakabhaka futhi ingamiswa phakathi kwama-poles we-magnet enamandla.
