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.
O2- would have the electron configuration of 1s2 2s2 2p6 Because the Oxygen has a charge of 2-, that means it has two more electrons than normal. So you do the electron configuration normally, then add two electrons! =]
Lithium (Li) has the electron configuration 1s2 2s1.
The electron configuration violates the aufbau principle, which states that electrons fill orbitals from lowest to highest energy levels. In this case, the 3s orbital should only have 2 electrons maximum before moving to the 3p orbital.
No, this electron configuration is not valid. The electron configuration should follow the Aufbau principle and Hund's rule. For the element with 3d5, it should be 1s2 2s2 2p6 3s2 3p6 4s1 3d5.
The investigator will find that 1s2 2s2 2p6 is the electron configuration for neon.

The electron configuration for nitrogen is written as 1s2 2s2 2p3.
Lithium (Li) has the electron configuration 1s2 2s1.
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)
