It's important because electrons, specifically valence electrons (the ones in the outer energy level) are the only part of the atom or ion that participates in a chemical reaction.
Aufbau theorized that electrons travelled in energy shells, hence the Aufbau diagram...
The principle is: electrons fill first the lower energy levels.
The principles that govern the building of an electron configuration include the Aufbau principle (electrons fill orbitals from the lowest energy level to the highest), the Pauli exclusion principle (each orbital can hold a maximum of two electrons with opposite spins), and Hund's rule (electrons occupy orbitals singly before pairing up). These principles help determine the arrangement of electrons in an atom's orbitals.
Each aluminum isotope has 13 electrons. In accordance with the Aufbau Principle those electrons will fill: 1s2, 2s2, 2p6, 3s2, 3p1. The shortcut notation is: [Ne] 3s2, 3p1.
Yes, the Aufbau principle applies to all elements. It states that electrons fill orbitals starting with the lowest energy levels before moving to higher energy levels. This principle helps to predict the electron configuration of elements based on the periodic table.

Electrons in an atom are distributed into different energy levels or orbitals based on the Aufbau principle, Pauli exclusion principle, and Hund's rule. Electrons fill the lowest energy levels first before moving to higher energy levels. The distribution of electrons in an atom's orbitals is determined by the electron configuration of that atom.

Answer: Aufbau Principal Aufbau Principal: fills from the lowest energy to the highest energy level
The principle is: electrons fill first the lower energy levels.
Add the electrons in accordance with the aufbau principle and then count the unpaired ones.
the aufbau principle
This is usually called the "Pauli Exclusion Principle".
Nature prefers low energy. It is thus energetically favorable to do so.
The Aufbau principle states that an electron will occupy the lowest energy orbital available before occupying higher energy orbitals. This principle helps to explain the filling order of electron orbitals in an atom.
The Aufbau principle states that electrons will fill up the different orbitals in an atom in order, i.e. the s orbitals of an atom will be filled by electrons before the p orbitals.
Electrons always enter to the lower orbit first,this is called auf bau principle.
