Oxygen
Oxygen is an important element in the combustion process. It is a member of the chalcogen group on the periodic table which is one of the most abundant elements in the Earth’s crust.
Oxygen is very important for a living organism to survive, multiply, and for converting food into energy. It is the only living gas for human beings and they inhale it from their nose reaching to their lungs.
Only oxygen gas gives our cells the ability to convert food into energy which is very important for us to survive.
Oxygen is a chemical compound with the symbol O and atomic number 8.
Properties of Oxygen:
- Oxygen gas is odorless, colorless and insipid in a normal state. Liquid oxygen is slightly paramagnetic. It is reactive and forms oxides with every element except helium, neon, krypton, and argon. It is moderately soluble in water.
- It is one of the common allotropes of oxygen.
- Trioxygen is the most reactive allotrope of oxygen that would cause damage to lung tissue. This allotrope is termed as ozone.
