8 Questions
According to the Aufbau Principle, in which order do the sublevels fill with electrons?
s < p < d < f
Why does an electron fill a 4s orbital before a 3d orbital?
Following the trend from lower energy to higher energy orbitals
What is the energy order of sublevels, from lowest to highest?
s < d < p < f
Why do electrons fill in the order they do, even if the energy levels are not in order?
As per the Aufbau Principle
Which sublevel has the lowest energy within an energy level?
s
In which order do electrons fill the orbitals according to the Aufbau Principle?
From lowest to highest energy
Why might a 6s orbital fill before a 4f or 5d orbital, even though the energy levels are not in order?
Because of the overlap of energy levels
Which sublevel has more energy, p or d?
d
Test your knowledge of the Aufbau Principle and electron subshells. Understand the order in which electrons fill subshells based on their energy levels and the number of orbitals within each subshell.
