Answer to Question #94874 in Organic Chemistry for Jason jeriel

Question

what principles or rules are violated in the following electronic configuration \\(1s^{2}2p_{x}^{2}\\)

Answer 1

The Aufbau Principle states that in the ground state of an atom, an electron enters the orbital with lowest energy first and subsequent electrons are fed in the order of increasing energies.

In case of atoms the energy increases in the order as 1s, 2s, 2p, 3s ,3p etc

Since in here the elctron is directly going to 2p instead of 2s. So it is being violated.
