Oxygen gas is free from odor, taste and color, combines with the majority of other elements, supports combustion, is very paramagnetic and has a pale blue color in both its solid and liquid forms. Oxygen is also a part of over 100,000 organic compounds.


Oxygen is a non-flammable gas that is colorless and odorless. It has a melting point of 54.36 Kelvin and a boiling point of 90.19 Kelvin. Oxygen speeds the rate of combustion by acting as an oxidizing agent.


A chemical property is a characteristic associated with a substance or reaction that is observable as it chemically changes or transforms into another substance. This chemical change produces a product that has a different composition than the original substance.


Examples of chemical properties include toxicity, flammability and chemical stability. Measuring these properties involves observing their effects on laboratory animals, testing with a flame or observing changes over time. In each instance, a chemical change occurs.


The properties of the oxygen family include the fact that, as atomic numbers increase, the elements in the family increase in metal similarity and decrease in electronegativity. All elements in the family exist in a natural state as ions.


Water is expressed by the molecular formula H2O and has a molar mass of 18.01 grams per mole. It has a density of 1 gram per cubic centimeter. The melting point of water is 32 degrees Fahrenheit, while the boiling point is reached at 211.96 degrees Fahrenheit.


According to the National Center for Biotechnology Information, the chemical formula for oxygen is O2. The O stands for the oxygen molecule, while the 2 represents the need for two oxygen molecules to form the element.


Hydrogen has several chemical properties; the molecular weight is 2.01594 grams and the relative density compared to air is 0.0695. Hydrogen's solubility in organic solvents is greater than it is in water. Hydrogen is more flammable than any other substance.


One of the main chemical properties of carbon is that it can easily bond with other elements in long chains. This the main reason is why carbon the basis for life on Earth.


Oxygen is required by all living things for respiration. It's also used in industries, water treatment, burning fuels and even protecting humans from harmful UV light thanks to the ozone layer.
