Particle vs. Molecule: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 28, 2024
A particle is a general term for a small piece of matter, while a molecule is a specific group of atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Key Differences

A particle is a broad term that can refer to any small piece of matter, atom, or molecule. In contrast, a molecule specifically refers to two or more atoms bonded together, forming the smallest unit of a chemical compound that retains its chemical properties.
