According to the Aufbau Principle, in which order do the sublevels fill with electrons?
According to the Aufbau Principle, in which order do the sublevels fill with electrons?
- d < f < s < p
- s < p < d < f (correct)
- p < s < f < d
- f < d < p < s
Why does an electron fill a 4s orbital before a 3d orbital?
Why does an electron fill a 4s orbital before a 3d orbital?
- As per the energy level arrangement
- Following the trend from lower energy to higher energy orbitals (correct)
- Because the 4s orbital has higher energy than the 3d orbital
- Due to the overlapping of energy levels
