Ernest Rutherford's Atomic Model

An atomic model is a proposed idea of what an arrangement of an atom thought to look like. Many physicists such as Dalton Billiard, J.J. Thomson, Ernest Rutherford, and Neil Bohr proposed these ideas and made models based on their own ideas. Out of these physicists, Ernest Rutherford’s planetary model is the most generally accepted atomic model. Ernest Rutherford is a New Zealand born son to a Scottish wheelwright and an English schoolteacher. He did well in school academically as a child and in 1894 was given an Exhibition Science Scholarship. This scholarship allowed him to go to Cambridge and study under J.J. Thomson. Under the help of Thomson, Rutherford came to discover radioactivity. Rutherford made a device used to detect electromagnetic …show more content…
He told that electrons give off light and “jump” between orbits in a nucleus. Many physicists believed this to be madness because they couldn’t visualize these electrons “jumping” orbits within an atom. They needed something that would actually back up the idea. Erwin Schrodinger decided something was not right with this model either. Schrodinger showed that electrons weren’t particles moving in an orbit at all and they certainly weren’t skipping orbits. He felt this model explained a hydrogen atoms’ spectrum, but the model needed more to understand about more difficult atoms. He believed no one was sure whether you could pinpoint an electron, but you could guess where it was. He stated that an electrons' location could be described as a cloud as they would be likely found in that …show more content…
H^ represents Hamiltonian operator that states all the energy within the system. ψ is what’s known as the wave function and E is all the energy binded together within the electron. The wave functions from each specific atom are called atomic orbitals. “Chemists define an atomic orbital as the region within an atom that encloses where the electron is likely to be 90% of the time” (Khan 8). This equation was used to calculate the energy in electrons. Even though this means the atomic orbitals aren’t right every time, Schrodinger’s equation was still used to calculate where they might lie. Schrodinger called his atomic model the Electron Cloud Model. It represents the nucleus surrounding a cloud. “The cloud” is essentially where any electron could lie within the atom. Using mathematical equations, it showed anyone one could predict where an electron was because the theory was that electrons come and go. They aren’t evenly spread out, or just stuck in one place. Nor do they orbit like
