Question #8510a
1 Answer
Aufbau Principle is one of the pillars of the Quantum Theory. Let's see what it means :)
Explanation:
Aufbau Principle is related to atomic orbitals. It states that, "when a certain atom is in it's ground state or lowest energy state, electrons enter the atomic orbitals in a sequence from low energy orbitals to high energy orbitals".
Now, the relative energy of an atomic orbital is given by the following expression:
Now, we have got
Now, the four Azimuthal quantum numbers are :
Now, more the
An additional knowledge: if
Accordingly, all the atomic orbitals are arranged according to the increasing order of their energies & electrons enter accordingly
Hope it Helps :)
