Atomic Models

Atomic models are theoretical representations of the structure of an atom. Key models include: Dalton’s Model: Atoms are solid, indivisible spheres. Thomson’s Model: The “plum pudding” model, where electrons are embedded in a positively charged sphere. Rutherford’s Model: Atoms have a small, dense, positively charged nucleus, with electrons orbiting around it. Bohr’s Model: Electrons orbit the nucleus in fixed energy levels or shells. Erwin Schrödinger Model: Electrons exist in probability clouds called orbitals, without definite paths, and their positions are described by quantum mechanics.
