Electron Orbital Model

Orbitals are the areas outside of the atomic nucleus where electrons are most likely to reside. They are characterized by different energy levels, shapes, and three-dimensional orientations. The location of electrons is described most generally by a shell or principal energy level, then by a subshell within each shell, and finally, by individual...

Atomic orbitals are three-dimensional regions around the nucleus where an electron is most likely to be found.

The first energy level is nearest to the nucleus and has the lowest energy. It contains a single spherical s orbital.

The second energy level contains four orbitals: one lower-energy 2s orbital and three higher-energy 2p orb...
