## anonymous one year ago What is a major difference between the quantum model of the atom and the Bohr model? A. Electrons orbit in elliptical orbits of varying distance from the nucleus. B. Electron orbitals are redefined as probable regions where the electron could be located. C. Electrons cannot transition between energy levels. D. Electrons eventually collapse into the nucleus.

not sure about quantum model of the atom? :/

2. Michele_Laino

it is option B, and such probability is given by the square of a special function, which is called the wave function

ohhh okie:) thanks!!

4. Michele_Laino

more precisely, we have: $\Large probability = {\left| \Psi \right|^2}$

ooh! thanks!
