Aufbau Principle

According to this principle the electrons are added one by one into the various orbitals in order of their increasing energy starting with the orbital of lowest energy.

'Aufbau' is a German expression which means building up or construction.

Increasing order of energy of the orbital:

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 6s, 4f, 5d, 6p, 7s
