Well, this was supposed to be called the Molecular Orbital Theory, or MO Theory.
The goal of molecular orbital theory is to describe molecules in a similar way to how we describe atoms, that is, in terms of orbitals, orbital diagrams, and electron configurations.
Humph, I wonder how it will be done...
Orbital diagrams are usually drawn to make things easier to understand. :D
O2
O
These 2 pictures are actually diagrams for O2 and O. They are oxygen! :p
Each line in the molecular orbital diagram represents a molecular orbital, which is the volume within which a high percentage of the negative charge generated by the electron is found.
-The molecular orbitals are filled in a way that yields the lowest potential energy for the molecule.
-The maximum number of electrons in each molecular orbital is two.
-Orbitals of equal energy are half filled with parallel spin before they begin to pair up.
It can usually be found in this equation:
