Dalton: Solid Sphere Model
John Dalton proposes the Solid Sphere Model of the atom, which states that atoms are solid, indivisible spheres with different masses and sizes. -
Thompson: The Plum Pudding Model
J.J. Thompson proposes the Plum Pudding Model of the atom, which states that atoms are made up of a positively charged sphere with negatively charged particles scattered throughout, similar to the raisins in a plum pudding. -
Rutherford: The Nuclear Model
Ernest Rutherford proposed the Nuclear Model of the atom, which states that atoms have a nucleus composed of positively charged particles surrounded by a cloud of electrons where electrons orbit a small, dense, positively charged nucleus. -
Bohr: The Bohr (Planetary) Model
Niels Bohr proposes the Bohr (Planetary) Model of the atom, which states that electrons orbit the nucleus in distinct shells, electrons orbit the nucleus in specific energy levels, and can jump between levels by absorbing or emitting energy. -
Schrodinger: Quantum Mechanics Model
Erwin Schrodinger proposed the Quantum Mechanics Model of the atom, which states that electrons exist as probability waves and can occupy multiple energy levels simultaneously instead of its precise location and path.
