Oxygen element is a reactive nonmetal that forms oxides with most of the other elements.At standard temperature and pressure, two oxygen elements combine with each other to form a stable molecule O 2 (i.e dioxygen).Chemical properties of OxygenĬhemical properties of oxygen are mentioned below. Ozone is bluish in color in gaseous as well as liquid state. The physical properties of oxygen and ozone are not the same.The other allotrope of oxygen is O 3 (ozone) which is found in the upper atmosphere of the earth. Dioxygen (O 2) is the most common allotrope of oxygen element which living organisms require for respiration.

Oxygen condenses at 90.188 K temperature and it freezes at 54.36 K temperature.And this solubility is also temperature dependent. Solubility of oxygen gas in water is more than that of nitrogen element.Oxygen appears pale-blue in color in its liquid state. Oxygen is a colourless, odourless and tasteless gas.

Physical properties of oxygen are mentioned below. The physical and chemical properties of oxygen element are mentioned below.

Oxygen molecules can withstand pressures as high as 19 million times the atmospheric pressure.

Plants produce oxygen by photosynthesis, but the majority of oxygen on the earth comes from the sea plants called phytoplankton.

The sea water contains approximately 4.95 ml of dissolved oxygen per litre.

Oxygen gas is present in the atmosphere (approximately 21%).

Oxygen element is the third most abundant element in the universe.

Hence ⅔ rd of the human body mass is because of oxygen. The number of hydrogen atoms are double than the oxygen atoms, but if we talk about the mass, then oxygen atoms have more mass as compared to hydrogen.

Because the human body is made up of 75% water, which includes oxygen and hydrogen molecules. Oxygen is also present in the human body in a very large proportion.Hence it is also said to be the helper of combustion. Oxygen gas does not burn itself, but helps in the combustion process.Ozone is another pure form of oxygen and it exists as O 3. Oxygen normally exists in a divalent molecule (i.e O 2).All living organisms including plants and animals require oxygen for survival.Oxygen is colorless gas, but it appears pale-blue in its liquid state.Interesting facts about oxygen element are mentioned below. So the last electron of oxygen enters the p-subshell or p-orbital. The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.įor example the electron configuration of oxygen is 2s 2 2p 4. How can you determine the blocks-wise position of elements?
