How did Schrodinger's model change Bohr's model of the atom?
Schrödinger's model changed Bohr's model from one of electrons travelling in fixed orbits to one in which electrons were most likely to be found only in certain regions of space.
In the Bohr model, the electrons are particles that occupy only certain orbits of fixed energy around the nucleus.
In the Schrödinger model, the electrons behave as standing waves that have greater probability of being in some regions of space (orbitals) than in others.
The electrons have fixed energies depending on the orbitals they occupy.
