energies of atomic orbitals

Single electron atoms - The relative energies of various orbitals of single electrons depend on the value of the principal quantum number 'n' and is independent of the value of 'l'. This can be shown by an arrangement known as energy level diagram. The diagra..

The combining atomic orbitals should not differ much in energies. For e.g., in case of homonuclear diatomic molecules of the type A 2 ' 2s-orbital of one atom can combine with 2s-orbital of another atom but 1s-orbitalh..

An atomic orbital is the space around the nucleus in which the probability of finding the electron is maximum. These most probable regions can be diagrammatically represented by cloud density (dot) diagrams. The density of dots (or lack of them) in any region of the cloud diagra..

Molecular orbitals are formed by the combination of atomic orbitals. But all types of orbitals cannot combine with each other. The following are the main conditions for effective combination of atomic orbitals: 1. The combining atomic..

The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (ii) the extent of overlapping between the atomic orbitals..

Atomic Orbitals - Electrons cannot exist at a particular point or in a well-defined orbit (path), according to the above new approach called wave mechanics. This led to the concept of 'most probable regions'. We talk about 'certain regions in space around the nucleus c..

According to LCAO method, the orbitals are formed by the linear combination (addition or subtraction) of atomic orbitals of the atoms, which form the molecule. This theory is applicable to hydrogen molecule as follows. Consider that hydrogen molecule co..

In the case of bonding molecular orbital, the attraction of both the nuclei for both the electrons is increased. This results in lowering of energy. In the case of antibonding molecular orbital, the electrons try to go away from the nuclei and this corresponds to repul..
