How to calculate the ionization energy?
Taking into account [Ar] 4s2 4p, calculate the ionization energy.
There are two main methods for calculating the ionization energy: 1) the method of subtracting the first two principal methods used by scientists to calculate the ionization energy is the method of subtraction. This method involves a little experimentation. First you must find the value of energy ion for which you are seeking. Then, subtract the value of the neutral atom energy. This difference is the ionization energy of the ions. Their responses may easily be compared with published literature values in most chemistry textbooks 2) Koopman's theory: The methods of the second primary in which scientists use to calculate the ionization energy using Koopmans' theory, a more advanced method. Two essential features of an atom or a molecule that is very important to scientists are the highest occupied molecular orbital (HOMO) and lowest occupied molecular orbital (LUMO). Together, these two orbitals are called frontier orbitals. HOMO can be found by locating the outermost electron orbital to see visual detail expaination the source code below:
