Quantum Mechanical Model (Erwin Schrodinger Model)

quantum mechanical model

In 1926, Austrian physicist Erwin Schrödinger (1887–1961) used the wave-particle duality of the electron to develop and solve a complex mathematical equation that accurately described the behaviour of the electron in a hydrogen atom. The quantum mechanical model of the atom comes from the solution to Schrödinger’s equation. Quantization of electron energies is a requirement … Read more

Rutherford’s Atomic Model (Plum Pudding Model)

rutherford's atomic model

Rutherford’s Atomic Model – The plum pudding model is given by J. J. Thomson failed to explain specific experimental results associated with the atomic structure of elements. Ernest Rutherford, a British scientist, conducted an experiment and based on the observations of this experiment, he proposed the atomic structure of elements and gave Rutherford Atomic Model. … Read more

Dalton’s Atomic Model | History, Discovery, Postulates

dalton's atomic model

Discovery of Dalton’s Atomic Model By far, Dalton’s most influential work in chemistry was his atomic model. Attempts to trace precisely how Dalton developed this model have proved futile. Even Dalton’s own recollections on the subject are incomplete. He based his theory of partial pressures on the idea that only like atoms in a mixture … Read more

J.J. Thomson Atomic Model | Postulates, Limitations

jj thomson atomic model

J.J.Thomson Atomic Model: J.J. Thomson proposed that an atom consists of a uniform sphere in which positive charge is uniformly distributed. The electrons are embedded into it in such a way as to give the most stable electrostatic arrangement. The sphere’s radius is of the order of 10-10 m, which is equal to the size … Read more

atomic model

Atomic Models: After discovering electrons and protons, the scientists started thinking of arranging these particles in an atom. Different models were proposed to explain the distribution of subatomic particles in an atom. There has been a variety of atomic models throughout the history of atomic physics that refers mainly to a period from the beginning … Read more
