Answer 1

It states that electrons are filled into atomic orbitals in the increasing order of orbital energy level. According to the Aufbau principle, the available atomic orbitals with the lowest energy levels are occupied before those with higher energy levels.

Answer 2

Answer:

Electrons in an atom are filled in the increasing order of their energies.

Explanation:

Aufbau principle is concerned with the energy of the atom and states that the electrons should occupy. The electrons occupy the orbitals in such a way that the energy of atom is minimum. or it can also be defined as the electrons in an atom are filled in the increasing order of their energies.
