jan 1, 1926 - Quantum Model
Description:
It was stated that electrons did not move around the nucleus on paths, but on waves, by Erwin Schrodinger. He said that it is impossible to know where exactly an electron is, by=ut we can find "clouds of probability" , called orbitals, to have some knowledge of where they could be. This is still widely accepted as the correct model of an atom.Added to timeline:
