After the 4d sublevel is completely filled, which electron sublevel begins to fill next?
A
4f
B
5s
C
5p
D
6s
Verified step by step guidance1
Recall the order in which electron sublevels fill according to the Aufbau principle, which states that electrons occupy the lowest energy orbitals available before filling higher energy ones.
Identify that after the 4d sublevel is completely filled, the next sublevel to fill is the one with the next lowest energy level.
Remember the typical filling order of sublevels: 4d is followed by 5p, not 4f or 5s, because 5p has lower energy than 4f and 6s comes after 5p.
Confirm that the 5p sublevel begins to fill after the 4d sublevel is full, as it is the next available sublevel in the sequence.
Therefore, the correct answer is the 5p sublevel, which fills immediately after the 4d sublevel.
