Build the ground-state orbital diagram for: hydrogen (H) Plan: • Look up the abbreviated (condensed) ground electronic configuration. • Use the electronic configuration to identify the outermost electrons. • 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 hydrogen is: 1s^1 All of the electrons are the outermost electrons: 1s^1 Follow Hund's rule by placing one alpha electron into the 1s orbital: Answer: | | 1s
