What is oxygen? It is a colorless, tasteless, odorless air element that comprises 21 percent of the atmosphere and is found in water, most rocks and minerals, and in many organic compounds. It is capable of mixing with all elements except inert gases and is particularly involved in combustion processes.
What are the Properties of Oxygen?
The chemical and physical properties of oxygen make it different from other elements. The most common substances, such as oxygen, are states, matter, solids, liquids, gases, and plasma. See the article on Oxygen Element for additional information and facts about this substance.
Physical and Chemical Properties of Oxygen
Physical Properties of Oxygen
Physical properties of oxygen are properties that can be observed without turning the substance into another substance. Physical properties are usually observed using our senses such as color, density, lightning, freezing point, boiling point, melting point, hardness, and smell. The physical properties of oxygen periodic table are given below;
- It is a colorless gas
- There are many known allotropes of oxygen including molecular oxygen O2 (normal atmospheric oxygen) and ozone (O3)
Ozone is a colorless gas
- Oxygen is an odorless gas
- Oxygen is tasteless gas
- It poor conductor of heat and electricity
- It slightly soluble in water, alcohol and some other common liquids
- It is denser than air. The density of oxygen is 1.429 grams/liter
- It has resistance to flow – stickiness. The viscosity of oxygen is 189 millipoises (at 0°C).
Chemical properties of oxygen
Chemical properties are those that determine how they react with other substances or change from one substance to another. The more we understand the nature of the substance, the better we can understand it. During the chemical reaction, we observed chemical properties. Reactions to materials can be brought about by changes brought about by burning, corrosion, heating, bursting, and damage. The chemical properties of oxygen are given below;
- Chemical Formula of Oxygen gas is O2 and for Ozone is O3.
- It is nonflammable.
- It supports combustion but does not burn itself.
- Oxygen occurs in many compounds, including water, carbon dioxide, and iron ore e.t.c.
- The common reaction in which it unites with another substance is called oxidation
Oxides of some metals form peroxides by the addition of oxygen.
Freezing Point of Oxygen
It present in gaseous oxygen form in normal temperature. It converts from a gaseous state to a liquid state at a temperature of -182.96°C when it takes on a slightly bluish color. Liquid oxygen can then be solidified or freeze at a temperature of -218.4°C
