On

The Aufbau Principle asserts that in the ground state of an ion, electrons fill the lowest possible energy atomic orbitals before moving on to higher levels.
This means that the lower-energy orbitals will be filled first, followed by the higher-energy orbitals.

Final answer:
Hence, the Aufbau Principle asserts that in the ground state of an ion, electrons fill the lowest possible energy atomic orbitals before moving on to higher levels.
