Respuesta :
The different atomic theory was given by Bohr, Dalton, Thomson, and Rutherford. The electron-cloud model stated that it is impossible to know the precise position of electrons. Thus, option D is correct.
What is the electron-cloud model?
The electron-cloud model is the modern atomic model that states the orbitals around the nucleus to the fuzzy clouds that are positioned in the atom. The probability of the electron depends on the denser areas.
This new model of atom focuses that the exact position of an electron cannot be determined rather its probable region can be determined. It was proposed by Erwin Schrodinger that falsified the electron to revolve in orbitals.
Therefore, Erwin Schrodinger's electron-cloud model states the position of an electron.
