What is Normality ?  Normality is the ratio of gram equivalent weight to volume of solution in liter.  where gram equivalent is the measure of reactive capacity of molecule consider for normality. Normality (N) :-                                  Gram equivalent weight  / Volume …

Aufbau Principle, Pauli Exclusion Principle and Hund’s Rule of Maximum Multiplicity

Aufbau Principle                               According to this principle in the ground state of the atoms the orbital’s are filled in order of their increasing energies means electrons enter higher energy orbital’s  so order in which orbital’s are filled is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, …
