Quantum Mechanical Atomic Model
The quantum mechanical model of the molecule originates from the answer for Schrödinger’s condition. Quantization of electron energies is a requirement in order to solve the equation. This is unlike the Bohr model, in which quantization was simply assumed with no mathematical basis.
The quantum mechanical model is a radical departure from that. Solutions to the Schrödinger wave equation, called wave functions.
The location of the electrons in the quantum mechanical model of the atom is often referred to as an electron cloud.
Keeping in mind the end goal to explicitly characterize the state of the cloud, it is standard to allude to the locale of room inside which there is a 90% likelihood of finding the electron. This is called an orbital, the three-dimensional region of space that indicates where there is a high probability of finding an electron.
The Schrödinger wave condition supplanted the Bohr thoughts regarding electron area with a vulnerability factor.
The location of the electron can only be given as a probability that the electron is somewhere in a certain area.
