The quantum mechanical model is the name of the atomic model in which electrons are treated as waves.
The Quantum model
The quantum mechanical model of the atom, also known as the electron cloud model, shows electrons as existing in certain regions of space called orbitals. These orbitals represent the probability of finding an electron in a specific location around the nucleus.
The Electron Cloud model
Bohr assumed that electrons moved in fixed orbits.
the modern description, primarily mathematical, of the behavior of electrons in atoms
According to the modern theory of quantum mechanics the electrons have a vibrating wave character and hence uncertain positions.Sometimes,they are close to the nucleus and sometimes away from it.Thus we can say that the paths of motion of electrons around the nucleus are not definite
The previous models of the atom, such as the Bohr and Rutherford models, described the atom as a miniature solar system with electrons orbiting around a nucleus. In contrast, the quantum mechanical model views electrons as existing in "clouds" of probability known as orbitals, where the exact location of an electron cannot be pinpointed but rather described in terms of probabilities. The quantum mechanical model also accounts for the wave-particle duality of electrons and incorporates principles of quantum physics.
The model of the atom based on Quantum Theory is often called the "Quantum Mechanical Model" or the "Quantum Model." This model describes the behavior of electrons around the nucleus as probabilistic, rather than in fixed orbits.
This is the quantum model of the atom.
The widely accepted model for the diagramming of atoms today is the Quantum model, which involves different orbits holding two electrons, and different energy levels, hold electrons in groups of 2, 8, 18, and 32. Drawing this model typically results in a huge mess of lines, and a three dimensional model would be even worse. So i suggest using the Bohr model, and making a semi-sphere with the correct number of electrons in each shell.
