hund's rule stats that electrons do not start paring untill all this orbitals are singly occupied.
Hund's rule was proposed by Friedrich Hund.
The rule that is violated in the configuration of 1s2 2s2 2px2 is the Hund's Rule. Hund's rule states that all electrons do not want to be with each other.
In 2004, 5-dehydro-m-xylylene (DMX) was the first reprted organic molecule known to violate Hund's rule.
Hund's Rule states that electrons will occupy orbitals of a subshell singly before any are doubly occupied. This is to maximize the total spin of the electrons in the subshell.
all other orbitals at that sublevel contain at least one electron (plato :P)
Aufbau
They do this before pairing up because of Hund's rule which says that the electrons occupy orbitals that have the same energy in a way that makes the number of electrons with the same spin direction as big as possible.

Hund's Rule
That depends on the number of electrons and protons
Hund's Rule
a hund is a dogIt means dog. "Der Hund" (male) or "die Huendin" (female)
