Quantum Atomic Model at it Again
Over the past centuries the quantum atomic model has been a coveted title of the scientific community. From John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, all the way up to the current quantum-mechanical model. What makes all of these scientists such a pivotal part of science after all? The quantum atomic model is one of the most important discoveries and innovations of all sciences. In this article we will go through the quantum model’s evolution from the early 1800’s all the way to present day. John Dalton is one of the first members of the scientific community to hold the honor of being an innovator of the quantum

Thomson was the next major innovator of the quantum atomic model. Thomson’s quantum atomic model is known as the Plum Pudding Model. Thomson theorized that negatively charged particles, called electrons, were suspended in a positively charged solution. Thomson’s theory was proven when he tested his hypothesis by what became known as the Cathode Ray Tube Experiment. During this experiment Thomson thought that electrons were evenly distributed throughout the atom. His discovery was based on the fact that the negatively charged cathode ray bent away from a positive charge. Thomson’s Cathode Ray Tube Experiment ended up in the discovery of the electron, the negatively charged subatomic …show more content…
This model is organized by number. Different numbers correspond to different elements of this specific model. These numbers can help determine the location of an electron in an atom. There are seven separate levels in which the valence electrons can be found. This is what makes up the current atomic theory model. This model is much more precise and accurate compared to models of previous times that were made by previous scientists. This current model is strongly backed by numerous experiments. Over the past centuries the quantum atomic model has been a coveted title of the scientific community. From John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, all the way up to the current quantum-mechanical model. All of the scientists involved in the evolution of the atomic theory model have some of the highest honors of the science community bestowed upon them. The quantum atomic model is one of the most important discoveries and innovations of all sciences. In this article we have gone through the quantum model’s evolution from the early 1800’s all the way to present
