Chemical Symbol vs. Chemical Formula: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 27, 2023
A chemical symbol represents a single element (e.g., H for Hydrogen), while a chemical formula shows the composition of a compound (e.g., H2O for water).

Key Differences

A chemical symbol is a one- or two-letter representation of an element, based on its Latin or English name. A chemical formula, on the other hand, is a combination of chemical symbols representing the composition of a chemical compound.
