Hund"s rule states the the electron pair up only after every orbital in a sublevel is inhabited by one electron.
This way that very first one electron rectal an orbit in the sublevel and only after ~ that, pairing start to take place in the orbital. For her understanding, I have given an instance to display how pairing that electrons wake up in, say the orbitals of “2p” sublevel.
↑ ↓= electrons
(Note that upper and down arrow represent electrons with opposite spins (+/-) as no two electrons in one orbital deserve to have the very same spin).
2p can accommodate 6 electron in 3 orbitals. Hence each orbital gets 3 pairs of electrons._ _ _ (The _ represent the 3 orbitals that 2p)2p↑ _ _ (First electron in an initial orbital) 2p↑ ↑ _ (Second electron)
2p↑ ↑ ↑ (Third electron)
2p↑↓ ↑ ↑(Pairing of electrons starts in first orbital)Hence pairing wake up after every of the three orbitals get occupied v one electron.
