According to this principle, the arrangement of electrons in increasing order of energy level is called the
Aufbau principle.

According to the Aufbau principle
, the first electron enters the
1s orbital
.

After the 1s orbital is complete, electrons enter the
2s orbital
.

Similarly, as shown in the figure, electrons enter the
2p orbital.
Similarly, electrons keep filling up gradually.

In any atom, the distribution of electrons in the
half-filled
configuration and the
fully-filled
configuration is uniform.
