Question

I have to fill in the blank

with the a term, short phrase or number

The Blank describes the sequence in which orbitals are filled.

Is it The Pauli exclusion principle??

No. The Pauli exclusion principle states that no two electrons may occupy the same energy position.

The Aufbau Principle

Answer 1

[AI-generated answer — Explain Bot]

The Aufbau principle is the rule that determines the sequence in which the orbitals of an atom are filled. According to the principle, electrons fill the lowest energy orbitals first before filling higher energy orbitals. This principle helps in understanding the electron configuration of atoms. To find the answer to the question, one can refer to a reputable source such as a chemistry textbook or an online resource that explains the Aufbau principle. A reliable source would provide a clear and accurate explanation of the principle and its significance in filling orbitals.
