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.
a maximum of 2 electron can be carried by s so it will be 1s2 2s2 2p6 3s2 3p6
Au 2s3
They have usually violated some social rule or taboo.
They violated rule number 1: Underestimating the enemy
innocent.. under judge. rights violated
The investigator will find that 1s2 2s2 2p6 is the electron configuration for neon.
Lithium electron configuration: 1s2 2s1, or in shorthand: [He] 2s1 Thus in LiF the Li cation (Li missing one electron to get its nobel gas configuration of He) it is Li+: 1s2 2s0, or in shorthand: [He] 2s0, This ion does NOT have 8 (octet) electrons, although it has a nobel gas configuration of He: 1s2.
It is the rule for filling of electrons in orbitals. It states that, When orbitals of equal energy (such as px, py, pz) are available electrons, they fill orbitals singly to keep the spin parallel. For example, N(Z=7)= 1s2, 2s2, 2px2, 2py1 (wrong) N(Z=7)= 1s2, 2s2, 2px1, 2py1, 2pz1 (correct)
For example, if Nitrogen has the electronic configuration 1s2 2s2 2p3; its trivalent because it needs 3 more electrons to complete its octect rule.
Warfare's NUMBER ONE RULE! Never underestimate the enemy. The British violated it.
I don't think you could trust her a long time before that.
