The Wonder of Molecules: From Simple to Complex

Molecules form when two or more atoms bond together.
The simplest molecule is hydrogen gas (H₂), made of just two atoms.
Water (H₂O) is a small molecule but essential for all life on Earth.
Carbon’s versatility allows molecules to grow into chains, rings, and networks.
Proteins are giant molecules built from thousands of atoms folded into shapes.
DNA, life’s blueprint, is a molecule billions of atoms long.
The size and shape of molecules decide how they behave and interact.
Molecules can store energy, carry information, or build structures.
Even tiny changes in a molecule’s structure can change its function completely.
From simple gases to complex biomolecules, molecules are the architecture of everything around us.
