Particle vs. Molecule: What's the Difference?
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.
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.
Particles can range from subatomic components like electrons and quarks to larger scale like dust or pollen. Molecules, however, are always made of atoms and are larger than individual atoms but still microscopic.
The properties of particles depend on their nature and can be physical (like dust) or subatomic. Molecules have specific chemical properties that define the substances they make up, like water molecules having different properties from oxygen molecules.
In physics, particles are studied in fields like particle physics, which includes elementary particles. In chemistry, molecules are central, with studies focusing on their formation, interactions, and reactions.
Particles are important in various scientific and industrial contexts, such as in air quality or nanotechnology. Molecules are crucial in chemistry and biology, important for understanding reactions, biological processes, and material properties.

In biology, molecules like DNA are crucial for life processes.
DNA molecules carry the genetic instructions for living organisms.
In physics, particles can be elementary, like electrons and quarks.
Scientists discovered a new subatomic particle in their experiments.
Chemical reactions involve the breaking and forming of molecular bonds.
Photosynthesis involves molecules of carbon dioxide and water transforming into glucose.
Particles can be visible to the naked eye or microscopic.
Microscopic particles are often involved in chemical reactions.
Molecules can be simple like O2 or complex like proteins.
Hemoglobin is a complex protein molecule that carries oxygen in the blood.
A very small piece or part; a tiny portion or speck.
The smallest particle of a substance that retains the chemical and physical properties of the substance and is composed of two or more atoms; a group of like or different atoms held together by chemical forces.
A very small or the smallest possible amount, trace, or degree
