A diagram illustrating the order in which atomic orbitals are filled is provided below. Here, \u2018n\u2019 refers to the principal\u00a0quantum number\u00a0and \u2018l\u2019 is the azimuthal quantum number.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" src=\"https:\/\/mdr.foobrdigital.com\/wp-content\/uploads\/2022\/06\/Aufbau-Principle.png\" alt=\"\" class=\"wp-image-5114\" title=\"Aufbau Principle\"\/><\/figure>\n\n\n\n<p>The Aufbau principle can be used to understand the location of electrons in an atom and their corresponding energy levels.

Also, the manner in which electrons are filled into orbitals in a single subshell must follow\u00a0Hund\u2019s rule, i.e. every orbital in a given subshell must be singly occupied by electrons before any two electrons pair up in an orbital.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the Aufbau Principle?
