What are the energies and positions of electrons according to the quantum mechanical model?

In the quantum mechanical model, electrons exist in defined energy levels or shells around the nucleus, characterized by quantum numbers that describe their energy, shape, and orientation. Instead of precise orbits as in the classical model, electrons are found in probabilistic regions called orbitals, where their positions are described by wave functions. These orbitals indicate the likelihood of finding an electron in a particular region of space at any given time. The energies of electrons are quantized, meaning they can only occupy specific energy levels, which are determined by the electron's interactions with the nucleus and other electrons.
