Atomic Models

Atomic models are conceptual frameworks that describe the structure of atoms, which are the building blocks of matter. Initially, atoms were thought to be solid spheres. Later developments revealed that atoms consist of a nucleus (made of protons and neutrons) surrounded by electrons that occupy specific energy levels or "shells." Electron configuration refers to how these electrons are arranged, influencing an atom’s chemical properties. Over time, models like Dalton's, Thomson's, Rutherford's, and Bohr's have evolved, reflecting a deeper understanding of atomic behavior based on experimental evidence. Today, quantum mechanics offers the most accurate depiction of atomic structure.
