Study Notes

Chemical Formula Basics

A chemical formula is a concise way to express the composition of a molecule using symbols and numbers.

Symbols in a Chemical Formula

Element symbols (e.g., H, C, O) can be used in a chemical formula.
Numerical subscripts can be used to indicate the number of atoms of an element in a molecule.
Parentheses can be used to group atoms in a chemical formula.

Chemical Formula vs. Chemical Name

A chemical formula represents the composition of a molecule using symbols and numbers.
A chemical name is a unique name assigned to a molecule, often based on its chemical structure.

Types of Chemical Formulas

The most basic type of chemical formula is the empirical formula, which shows the simplest whole-number ratio of atoms in a molecule.
A molecular formula specifies the actual number of atoms of each element in a molecule.

Structure Specification

A chemical formula can fully specify the structure of a molecule, including the arrangement of atoms and bonds.
