Quantum Wave Model

Electron Configuration 4 subshells S, P, D, F

S Subshell Spherical in Shape – enables the electrons to surround the nucleus of the atom Lowest energy level 1 orbital (each orbital holds 2 e-) Holds 2 e-

P Subshell Dumbbell shaped and can be oriented in space in one of three ways. 3 orbitals (each orbital holds 2 e-) Holds up to 6e-

D Subshell Dumbbell shaped 5 orbitals (each orbital holds 2 e-) Holds 10 e-

F Subshell Dumbbell shaped Greatest energy 7 orbitals (each orbital holds 2 e-) Holds 14 e-

Orbital Diagrams Orbital Diagrams: Electrons enter the electron configuration (orbital diagram) pattern beginning at the lowest energy and filling the pattern to the highest energy.

Hund’s Rule Hund’s Rule: Electrons enter the each orbital individually until all orbitals are half filled before pairing with other electrons in the subshell. In other words – one electron per orbital until all orbitals are filled, then 2 nd electron can be placed in each orbital.

Pauli Exclusion Principle Pauli Exclusion Principle: an orbital can contain no more than two electrons and those two electrons must be paired, In other words, electrons must have opposite spin (usually indicated by one up-arrow and one down-arrow).
