What you can learn
- A molecular formula tells you how many atoms of each element are joined.
- The same atoms can only make certain stable molecules.
- Atoms are shown as balls and bonds as sticks.
Frequently asked questions
What is a molecular formula?
A list of the elements in a molecule and how many atoms of each, such as H₂O for two hydrogens and one oxygen.
Why can't I make any combination of atoms?
Atoms form a fixed number of bonds (valence), so only certain combinations make stable molecules.
