What is the principle regarding the filling order of orbitals in atoms' ground states?

Options

  1. AElectrons fill orbitals randomly.
  2. BElectrons occupy the highest energy orbitals first.
  3. CElectrons fill orbitals in order of decreasing energy.
  4. DElectrons fill orbitals in order of increasing energy.

Correct answer

D. Electrons fill orbitals in order of increasing energy.

Step-by-step solution

"In the ground state of the atoms, the orbitals are filled in order of their increasing energies."
