Chemical Formula
The atomic composition of
molecules can be described and shown in either:
- Words:
' Each molecule of Carbon Monoxide is made up of one Carbon atom and one oxygen
atom'
- Chemical Formula
'CO'
Chemical formulas are useful
for Chemical Equations, and are easier to see. Some common examples are shown
here:
- Water Molecule (H2O)
- Oxygen Molecule (O2)
- Ozone Molecule (O3)
- Carbon Monoxide (CO)
- Carbon Dioxide (CO2)
