The word 'aufbau' in German means 'building up'. Here, it refers to the filling up of orbitals with electrons.

Answer 2

This principle states that the electrons are filled in the barriers for orbitals in an increasing order of their energies nai orbitals having lowest energy will be filled first and the orbital having highest energy is will be filled last.
