Question

Draw the aufbau principle diagram.

Answer 1

Aufbau Principle is the basic Principle based on the n + l rule which is used for filling the electrons from lower energy level to the higher Energy levels.

The Aufbau is the Greek word which means climb up. This Rule tells us that electrons climbs up from lower energy level to higher energy level.

This Principle have many significance, as it has made the method of arranging the electrons easy.

The Electronic configuration which may be defined as the arrangement of the electrons in an atom is systematically told by the Aufbau Principle.

The increasing order of atomic orbital in which electrons will be filed are,

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

The Chart for determining the lower energy level and higher energy level and the way in which electrons will be filled is shown in attachment.

Hope it helps.

Answer 2

Hey brainly user

Here is your answer

Aufbau principle

Aufbau is a German word which means building up or construction

Statement : In the building up of atoms the electrons enters into the various orbitals in the increasing order of the their energies

The orbital with the lower energy is filled up first followed by the orbitals of higher energy
