Oxygen( आक्सीजन ) 

यह वायुमण्डल मे पायी जाने वाली सबसे महत्वपूर्ण गैस है |इस गैस के बिना किसी भी जीव ,जन्तु ,मानवकी कल्पना नहीं की जा सकती || इस गैस को को प्राणवायु और जान गैस भी कहा जाता है |






• Physial Properties(मुख्य गुण)


1. रंगहीन
2.गंधहीन 
3.स्वादहीन 
4.आपेक्षिक भार =1.1
5.Critical Temperature = -119•C
6. Critical Pressure = 50 atm
7.अत्यंत   सक्रिय गैस
