The Orbital Notation Calculator is a powerful tool designed to assist in understanding the electron configuration of atoms. By inputting the atomic number of an element, users can generate the corresponding orbital notation, providing a visual representation of how electrons are distributed across different energy levels and orbitals within an atom.
Formula of Orbital Notation Calculator
The order of filling orbitals follows the Aufbau principle, Hund’s rule, and the Pauli exclusion principle.
The formula for calculating the maximum number of electrons in a given shell (n) is:
Maximum electrons = 2n^2
For example, for the first shell (n=1), the maximum number of electrons is:
Maximum electrons = 2(1)^2 = 2
For the second shell (n=2), the maximum number of electrons is:
Maximum electrons = 2(2)^2 = 8
And so on.
To represent the orbital notation for a specific atom, you would fill the orbitals following the order of filling and the rules mentioned above. For example, for the electron configuration of carbon (C), which has 6 electrons, the orbital notation would be:
1s^2 2s^2 2p^2
This notation indicates that the first shell (n=1) is filled with 2 electrons in the 1s orbital, and the second shell (n=2) is filled with 2 electrons in the 2s orbital and 2 electrons in the 2p orbital.

Example of Orbital Notation Calculator
Let’s consider the element oxygen (O), which has an atomic number of 8. Using the Orbital Notation Calculator, we can determine its electron configuration:
1s^2 2s^2 2p^4
This notation shows that oxygen has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, and 4 electrons in the 2p orbital.
