Orbitals of electrons in atoms differ in size shape and orientation. Definite energies and angular movements characterize atomic orbitals. The state of an electron in any atom is defined by certain permissible values of energy and angular momentum, which describe its location wi..

Magnetic Quantum Number (m) - This quantum number describes the behavior of the electrons in the magnetic field. We know that the movement of electrical charge is always associated with magnetic field. Since the revolving electron possesses angular momentum, ..

The magnetic quantum number describes the behaviour of electron in a magnetic field. In the absence of external magnetic field electrons / orbitals having same values of 'n' and 'l' but different values on 'm' have the same energies. They are called degenerate or..

) the orientation of the orbital (m) and the direction of its spin (s). In other words, these quantum numbers serve as an address for an electron. The various permitted values of the quantum numbers are summarized below: Quantum numbe..

For 'd' orbitals 'l' = 2. Therefore the angular momentum of an electron does not show a spherical symmetry. For 'l' = 2, five values of 'm' the magnetic quantum number exists i.e., -2, -1, 0, +1, and +1. Accordingly there are five space orientations for 'd' orbit..

Shapes of Atomic Orbitals - 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 an..

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 illustrates th..

For 'p' orbitals 'l' = 1. So,..

This principle was proposed by Pauli in 1952. It states that no two electrons in an atom can have same values for all the four quantum numbers. Thus, in the same atom, two electrons may have the same values for three quantum numbers but the fourth must be dif..
