f electron orbitals cubic set computer model An electron orbital is a region around an atomic nucleus not seen in which one or a pair of electrons is most likely to exist The f orbitals are unusual in that there are two ways to represent the orbital shapes In the cubic set the bottom four orbitals are eightlobed The three upper orbitals have lobes with encircling cones The general set is shown in image A The f orbitals are partially filled in the Actinide metals
