Bohr's Atomic Model And The Electron Cloud Model

There have been many models constructed by scientists who have tried to figured out how an atom is made up and what exactly it is made up of but two of the best atomic models of the atom are Bohr’s atomic model and the Electron cloud model which were both made in the early 1900s . In 1913 the Danish physicist Niels Bohr had created Bohr’s atomic model showing the atom and how it was structured. Bohr’s atomic model was the first known model of an atom that incorporated the quantum theory and also was the predecessor for the wholly quantum- mechanical models that were constructed many years later. Before 1913 it was thought of that an atom had a nucleus with electrons orbiting around it in a circular motion, but this was not the case. It was…show more content…
This principle also states that the concepts of exact position and exact velocity do not have a meaning in nature. Another problem in Bohr’s atomic model was that there should have been charged electrons that were moving around the nucleus radiating energy because of the acceleration of their orbit but his model had no evidence of that occurring. One of the third main problems in Bohr’s atomic model was that frequency lines did not show overtones or patterns. In Bohr’s model of the atom was that the frequency of the electrons did not have a set pattern or even follow a pattern for that matter but instead were scattered all around the atom. Bohr’s atomic model was one of the best created and devised scientific models of the atom in his lifetime considering it brought a large amount of new knowledge to the scientific community. For the previous reasons that are stated above they show why his model of the atom and how everything works together couldn’t necessarily be the correct model because it didn’t follow the previous rules that were discovered and tested on the atom that were found to be…show more content…
In 1926 an Austrian physicist, Erwin Schrödinger, created the Electron cloud model of the atom after calculating many mathematical equations that described the likelihood of discovering an electron that was located in a certain position of the atom. Before the Electron cloud model was created, Erwin Schrödinger wrote a group of papers covering the concept of wave functions and mechanics. The Schrödinger Equation came from the information that was written in these papers. The Schrödinger Equation was a mathematical formula that would be able to describe how the quantum state of a quantum system ends up changing through the course of time. This information that was concluded throughout the writings of the papers and the creation of the Schrödinger Equation became the basis for the Electron cloud model of the atom that became a large scientific breakthrough on how an atom operates and what it consists of. Schrödinger’s model consisted of a very dense nucleus that was surrounded by a group or cloud of electrons at many differing levels in their orbit around the nucleus. This model was mainly derived from theories and probability because of the fact that many mathematical equations were done to figure out exactly where each electron in the atom would end up, what level they would get to, etc. The Electron cloud model did not give information as to how to define the exact path
