Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element and oxidizing agent that readily forms compounds (notably oxides) with most elements. Photosynthesis releases oxygen, and respiration consumes oxygen.
The structure shown above is oxygen's cubic crystal element structure. Oxygen exists in all three forms-liquid, solid, and gas. The liquid and solid forms are a pale blue colour. However, oxygen gas is colourless, odourless, and tasteless.The elemental structure is a cubic crystal shape. Oxygen changes from a gas to a liquid at a temperature of 182.96Â°C, and then can be solidified or frozen at a temperature of -218.4Â°C. Oxygen exists in all three allotropic forms.owever, oxygen gas is colourless, odourless, and tasteless. The elemental structure is a cubic crystal shape.
