An integer for 0 to n-1 that is related to the shape of an atomic orbital.
Angular momentum quantum number
A mathematical expression that describes the motion of the electron's matter-wave in terms of time and position in the the region of the nucleus. The term is used qualitatively to mean the region of space in which there is a high probability of finding the electron.
Atomic Orbital
The nuclear charge an electron actually experiences as a result of shielding effects by other electrons.
Effective Nuclear Charge
A principle developed by Wolfgang Pauli stating that no two electrons in an atom can have the same set of four quantum numbers. The principle arises from the fact that an orbital has a maximum occupancy of two electrons and their spins are paired.
Exclusion Principle
A specific energy state of an atom given by the principal quantum number n.
An integer from -l through 0 to +l that specifies the orientation of an atomic orbital in the three-dimensional space about the nucleus.
Magnetic Quantum Number
A positive integer that specifies the energy and relative size of an atomic orbital.
Principle Quantum Number
A number, either +1/2 or -1/2, that indicates the direction of electron spin.
Spin Quantum Number
An energy substate of an atom within a level. Given by the n and l values, the sublevel designates the size and shape of the atomic orbitals.
