Question

What were Erwin Schrodinger's contributions to the modern day atomic model?

"oint out which contributions are present in the modern atomic model and which were eventually disproven and thus are not part of the modern model."

Answer 1

This atomic model is known as the quantum mechanical model of the atom. Unlike the Bohr model, the quantum mechanical model does not define the exact path of an electron, but rather, predicts the odds of the location of the electron. This model can be portrayed as a nucleus surrounded by an electron cloud. Where the cloud is most dense, the probability of finding the electron is greatest, and conversely, the electron is less likely to be in a less dense area of the cloud. Thus, this model introduced the concept of sub-energy levels.
