OXYGEN
BASICS
atomic number: 8
atomic mass: 16,00
-discovered in 1772 by Carl Wilhelm Scheele
-most abundant element in Earth's crust
PHYSICAL PROPERTIES
Colorless, odorless, and tasteless gas
tb: -183℃ → below it becomes a pale blue liquid
tm: -218℃ → becomes a solid
𝝆(20°): 1,308 g/cm3
Ei: 1313,95 kJ/mol
CHEMICAL PROPERTIES
not flammable
Supports combustion
not especially reactive at room
temperature and standard pressure
The atomic species, O, is far more reactive
forms chemical bonds with almost all other elements
Importance and uses of oxygen
vital for respiration and other biochemical processes in living organisms
important for all combustion process, such as the burning of the hydrocarbon
fuels (oil, coal, petrol, natural gas)
as an oxidizing agent for use in missiles and rockets
Oxygen preparation in industry
fractional distillation
electrolysis
produced during photosynthesis by plants:
