Bohr date of discovery

WebDemocritus’ most important contribution to modern science is considered to be his atomic theory. This theory lays down that the entire universe and all existing matter exist by the principles listed below. Everything is made up of atoms, and these atoms are physically indivisible. There is empty space that exists between atoms. WebIn the Bohr Model the electron is treated as a particle in fixed orbits around the nucleus where as Schrodinger’s model treated the electron as a wave that occupies three dimensional space. This expanded the understanding of the electron to have 4 quantum numbers. The quantum numbers of an electron give it its own identity and these …
