Q: The Madelung Rule
The [...] can be predicted by [...] for each orbital.
A: (relative) energies of the orbitals; the sum of n+1
Back Extra: According Rules:
a. Orbitals are filled in order of increasing n+1
b. If two orbitals have the same value of n+1, they are filled in order of increasing n

Q: Aufbau Principle:
In the ground state of an atom or ion, electrons fill atomic orbitals of the [...] energy levels [...] occupying higher levels.
A: lowest available; before
