Answer:
behave as waves and the probability of finding the electron is determined by the factor, ψ²
Explanation:
Erwin Schrödinger proposed quantum mechanical model of atom in which electron behave as waves. He introduced ψ, which is the amplitude of the wave of the coordinates (x, y ,z ). ψ² represents probability of finding the electron in the given region above within the atom.
The atomic orbital is the region within the atom which encloses where electron is more than 90% probability.
