Orbital

A molecular orbital is a mathematical function that describes about the wave nature of electrons. It can be used to calculate the probability of finding an electron in a molecule. A molecular orbital is formed by combining atomic molecular functions. There are various types of orbital in accordance with the new energy level generated by combining functions. It is described as the form of electron clouds. If the phases of electrons in a molecule are different, it forms a node among electron clouds where the probability of finding an electron becomes zero (0).

- HOMO: Highest Occupied Molecular Orbital
- LUMO: Lowest Unoccupied Molecular Orbital
