Finn Price · Answer 1

Option C:Scientist cannot predict the exact path of an electron within an electron cloud using current atomic models.

The current model gives a probaility of finding an electron in a region, but is is not possible to determine the location and velocity of the electron.

Jason Liu · Answer 2

The quantum mechanical model of the atom states that the location of the electrons around the atom cannot be precisely determined. The region where the electron can probably be found is known as the electron cloud.
