3. Oxygen is a chemical element that is a gas with no
smell or color. Its atomic number is 8 and its atomic
mass is 16.
Our atmosphere is made of mostly 02, which our
bodies have evolved to breathe.
Oxygen is very important because most living things
need it to survive. It is the key for generating energy
in cellular respiration.

4. Examples of oxygenExamples of oxygen
Oxygen occurs in all kinds of minerals. Some common
examples include the oxides, carbonates, nitrates,
sulfates, and phosphates. Oxides are chemical
compounds that contain oxygen and one other
element.

5. Oxygen is a chemical
element with an atomic
number of 8 (it has eight
protons in its nucleus).
Oxygen forms a molecule
(O2) of two atoms which is a
colorless gas at normal
temperatures and pressures.
Oxygen atoms are very
reactive, and are incorporated
into many common chemical
compounds, such as water
(H2O), carbon dioxide (CO2),
carbon monoxide (CO), sulfur
oxides (SO2 and SO3), and
nitrogen oxides (NO and NO2).
