Document Summary

The electron configuration of be, b, and c: Repulsion between the two 2p electrons in c is minimised when the electrons have the same spin they are in different orbitals. Electrons in different orbitals are further apart, on average, than electrons in the same orbital. Electrons with the same spin avoid each other and thereby minimise repulsion. The ground state electron configuration of all the atoms is determined in this way the aufbau principle ( building up ) 1s, 2s, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s. Determine ground state electron configurations for the following atoms. Use the noble gas shorthand notation (except in case of ne). The electro configuration of ar determines the core of fourth row electrons. The electron configuration of fourth row elements is then written as [ar] followed by the valence configuration. Chromium and copper are the two exceptions to the orbital filling order that occur in the first 40.
