orbitals in energy level 2

Energy Level Diagram for Molecular Orbitals - The relative energies of molecular orbitals depend upon the following two factors: (i) the energies of the atomic orbitals combining to form molecular orbitals. (i..

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 orbital..

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 diagram given below illu..

>a 2s orbital differs from 1s orbital in being larger in size and having a nodal surface . The higher s orbitals have also spherical shapes and number of nodal surfaces in s orbital for any given energy level is n - 1, where n re..

Shapes of p orbitals - For p-orbitals (l=1), there are three possible orientations corresponding to m = -1, 0, +1 values. This means that there are three p - orbitals in each p-subshell. These are designated as p x , p y and p z ; For e.g., 2p x , 2..

The energy of electron revolving in a stationery orbit is of two types. Kinetic energy due to velocity and potential energy due to the position of the electron. Now (-ve is for charge of an electron) Now T.E = K.E + P.E Spectral series ..

The following rules are followed for filling up molecular orbitals with electrons in order to write molecular configurations: 1. The molecular orbital having the lowest energy is filled first. This is in accordance with Aufbau principle as already discussed for atoms. ..

> It has lesser electron density in the region between the two nuclei of the atoms The forces in this orbital tend to bring the two nuclei of the atoms together. Therefore, electrons in the bonding MO contribute to attraction between the two atoms The forces ..

Covalent bonds are formed by the overlap of atomic orbitals. As orbitals have different shapes, it is difficult to represent the actual shape of the orbitals on the paper. Hence a pictorial notation is adopted with the following rules: An orbital is repres..

Conditions for the Combination of Atomic Orbitals - 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 o..
