2 mar 2019 · In the early 1900s, scientists including J.J. Thomson, Ernest Rutherford, Niels Bohr, and Erwin Schrödinger developed models of the internal structure of atoms. Thomson's plum pudding model depicted atoms as positively charged spheres containing electrons.

19 kwi 2021 · Each model built on previous work and provided new insights about atoms, such as Dalton's billiard ball model, Thompson's plum pudding model, Rutherford's nuclear model, Bohr's planetary model, and Schrodinger and Heisenberg's quantum mechanical model describing electrons as waves.
17 lis 2014 · This document outlines the development of atomic theory from ancient Greek philosophers to modern physics. It describes key contributors such as Democritus, Dalton, Thomson, Rutherford, Bohr, and Schrodinger who proposed models of the atom based on experiments.
4 Heisenberg’s Uncertainty Principle The position and speed of a moving object cannot BOTH be known exactly at the same time.
After Schrödinger had shown the mathematical equivalence of wave mechanics, which he had discovered, with quantum mechanics, the fruitful combination of these two different areas of physical ideas resulted in an extraordinary broadening and enrich-ment of the formalism of the quantum theory.
Like the 5 Postulates, there are NO physical assumptions available to “derive” the Schrödenger Equation. Just like Newton’s law of motion, F=ma, and Maxwell’s equations, the Schrödenger Equation was proposed to explain several observations in physics that were previously unexplained.
27 Summary We have introduced the Schrödinger equation – the equation of motion of quantum mechanics and “the whole of chemistry.”* The time-independent Schrödinger equation parallels Hamilton’s equation in classical mechanics and physically represents conservation of energy.
