AN INNOVATIVE AND RAPID METHOD FOR EVALUATION OF UNPAIRED ELECTRON NUMBER OF HOMO AND HETERO NUCLEAR DIATOMIC MOLECULES AND IONS WITHOUT USING M.O.T

Unpaired electron number is one of the vital important terms used in the field of chemistry. Determination of unpaired electron number is very important in different kinds of problems, such as for finding the magnetic moment (in B.M.), for finding spin multiplicity value etc. But evaluation of unpaired electron number using MOT or by drawing molecular orbitals, is time consuming. So, in this manuscript, I have tried to represent a simple and rapid way to calculate the unpaired electron number with the help of applied mathematics and some basic concepts of chemistry, which can be used especially for any competitive exam, that will be beneficial for all students to save their valuable time. To use this new method, the student need not compulsorily know the MOT. This method is applicable for those diatomic molecules and ions, which have their total electron number (01-20).
