![Build the ground-state orbital diagram for: oxygen (O) Plan: • Look up the abbreviated (condensed) ground electronic configuration. • Use the electronic configuration to identify the outermost electrons. • Determine the energetic ordering of atomic orbital subshells. • Use the following representations: a gray rectangle for an atomic orbital, an up arrow for an alpha (spin-up) spin state and a down arrow for a beta (spin-down) spin state. • Follow the Pauli exclusion principle by representing the first electron in each atomic orbital with an alpha spin state and the second electron with a beta spin state. • Place electrons into orbitals following the Aufbau principle and Hund's rule. The abbreviated ground electronic configuration for oxygen is: [He]2s^22p^4 Electrons in atomic orbitals outside of the helium core, [He], are the outermost electrons: 2s^22p^4 Atomic orbital energy usually increases from 1s to 8s in the following order: Follow the Aufbau principle by filling the atomic orbitals with electrons in the following order: 2s < 2p Place two electrons as an alpha-beta pair into the 2s orbital: 2s Place four electrons into the three 2p orbitals with one alpha electron in each of the three orbitals and one beta electron in one of the orbitals: Answer: | | 2p 2s](../image_source/24ae0ccc525ac474263df167bf19f678.png)
