Quantim Mechanics is abranch of mathematical physics that deals with the emission and absorption of energy by matter and with the motion of material particles. Because it holds that energy and matter exist in tiny, discrete amounts, quantum mechanics is particularly applicable to Elamentry Pprticl...

Our understanding of the atom has changed remarkably over time. At one point, it was considered a solid object. Now, the atom is considered to have a cloud for its electrons. We believe that our notion of the atom has had many changes, and will continue to change until we get it right. The ...

The History Behind The Atom Throughout the discovery of the atom, many scientists worked to formulate how the atom works. Which began in the early 1800's with John Dalton, to our current model of the electron cloud developed by Schrodinger. During this long process of the discovery th...
