Chemical Formulas

Empirical Formula- The formula of the compound with the smallest whole number ratio of atoms
Molecular Formula- Tells the number and type of atoms in a molecule
Structural Formula- Shows the structure of a molecule and how the atoms are bonded or connected
- The smell of a compound is usually related to the structure of a molecule
- Molecules can have the same molecular formula, but different structural formulas- these are called isomers
