How to Use the Hund’s Rule Calculator
Using the Hund’s Rule Calculator involves the following steps:
- Input Total Number of Electrons (e): Enter the total number of electrons present in the atom or molecule. This number is crucial for determining how electrons will be distributed.
- Input Total Number of Orbitals (o): Provide the total number of orbitals available for electron distribution. This reflects the number of spatial regions where electrons can be found.
- Calculate Electron Distribution (ED): Click the “Calculate ED” button to compute the electron distribution using the formula:ED = (e / o) + (e(p) * o)Here, e / o represents the average number of electrons per orbital, and e(p) * o adjusts this value based on the number of orbitals.
- View Result: The result will show the electron distribution, helping you understand how electrons are arranged across orbitals.
