Full Electron Configuration: 1s¹
Noble Gas Configuration: [He]¹
Explanation:
* Full Electron Configuration: This lists all the orbitals and their electrons. Hydrogen has only one electron, which occupies the 1s orbital.
* Noble Gas Configuration: This uses the previous noble gas on the periodic table as a shorthand. Helium (He) is the previous noble gas, and its configuration is 1s². We then add the remaining electron from hydrogen, giving us [He]1s¹.
