WebAn orbital energy level diagram (or just orbital diagram) shows the relative energies of orbitals and how electrons are distributed among orbitals within a subshell. In an orbital energy level diagram, individual orbitals are usually represented by horizontal lines whose vertical position conveys the qualitative relative energies of the orbitals. WebWhen two atomic orbitals come in contact, they may form a sigma bond, pi bond, delta bond, or other form of interaction. These atomic orbitals may undergo in-phase overlap to produce a bonding orbital, as well as out-of-phase overlap to produce an antibonding orbital.
