... Electrons have a magnetic moment. Consequently, many atoms (e.g., iron) do as well. However, atoms that have completely filled orbitals never have a magnetic moment (in isolation). Why is this? An orbital is a set of states, all with the same (n,l). There are 2l+1 ml values and 2 ms values. When the ...

Molecular orbital
In chemistry, a molecular orbital (or MO) is a mathematical function describing the wave-like behavior of an electron in a molecule. This function can be used to calculate chemical and physical properties such as the probability of finding an electron in any specific region. The term orbital was introduced by Robert S. Mulliken in 1932 as an abbreviation for one-electron orbital wave function. At an elementary level, it is used to describe the region of space in which the function has a significant amplitude. Molecular orbitals are usually constructed by combining atomic orbitals or hybrid orbitals from each atom of the molecule, or other molecular orbitals from groups of atoms. They can be quantitatively calculated using the Hartree–Fock or self-consistent field (SCF) methods.
