The Atom

The Atom The basic idea of the atom was adopted by scientists thousands of years later because it explained new discoveries in the field of chemistry. Long after chemical atoms were found to be divisible, and even after smaller, truly indivisible particles were identified. Over time theories of the atom changed. The nature of atoms in philosophy varied a lot over time and between cultures and schools. The Plum Pudding Model was proposed in 1904 before the discovery of the atomic nucleus in order to add the electron to the atomic model. In this model, the electrons were free to rotate within the blob or cloud of positive substance. These orbits were stabilized in the model by the fact that when an electron moved farther from the center of the positive cloud, it felt a larger net positive inward force, because there was more material of opposite charge, inside its orbit.
There was the Bohr Model which depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus that seemed to have a similar structure to the solar system, but with attraction provided by electrostatic forces instead of gravity. The Bohr Model has been put to rest, but the quantum theory remains sound. The Bohr model was a primitive version of the Hydrogen atom. The Bohr model is still commonly taught to introduce students to quantum mechanics.
The Wave Model was created by Schrodinger and he had written the wave equation to describe the new mechanics of particles. The model was more of a mathematical model rather than a physical model. The equation is useful to predict some properties of objects, but is not able to describe the object itself. The Manhattan Project is the action of splitting an atom. The splitting of an atom releases a huge amount of energy creating a massive explosion. This explosive splitting of an atom became the first of several atomic bombs.
