WebMay 5, 2024 · What does Hand’s rule state? Select the correct answer below O No two electrons in the same atom have the exact same set of quantum numbers. O Electrons fill degenerate orbital’s singly first before pairing. O Electrons fill orbital’s in increasing energy order O Electrons are most likely to be found in regions of space called atomic ... WebIf orbitals of equal energy ( i.e. degenerate orbitals) are being filled, the electrons are placed into each orbital in the degenerate set before they are spin paired with another electron in the same orbital In simple terms, Hund's rule requires single occupancy before pairing.

When filling orbitals of equal energy electrons fill singly first?
WebSep 16, 2024 · The combination of n atomic orbitals generates n molecular orbitals. In the most simple case two atomic orbitals interact to generate two molecular orbitals. One of these molecular orbitals is bonding in nature and thus energetically more favorable than the contributing atomic orbitals, the second one is antibonding and energetically less … WebHund’s Rule indicates that as electrons are added to an atom, electrons tend to half-fill orbitals of the same energy level BEFORE pairing with existing electrons to fill orbitals. This means every orbital in a sublevel is singly occupied before any orbital is doubly occupied. All of the electrons in singly occupied orbitals have the same spin. WebJan 25, 2024 · Ans: According to the Aufbau principle, the electrons in the ground state of an atom tend to occupy the accessible orbitals in increasing order of energy, with the lower energy orbitals being filled first.
