Beginning in the early nineteenth century, scientists developed models to explain the structure of the atom. As more information was discovered about the nature of the subatomic particles of the electron, proton, and neutron, the model of the atom was continuously refined and revised. We will take a look at how the atomic models of Dalton, Thomson, Rutherford, and Bohr eventually evolved into the current-day Quantum Mechanical model of the atom.
It is a phenomenon in which compounds have same moleculer formula but different structural formula due to which they posses different physical and chemical properties.
