CHM 1045 Lecture Notes - Lecture 8: Effective Nuclear Charge, Electron Configuration, Diamagnetism
Document Summary
The 1s sublevel must be filled before electrons are placed in the 2s orbital. The 3d orbital are generally filled after the 4s orbital. The electron ______ of an element shows the distribution of electrons within the electronic energy levels of the atom. The ground-state electron configurations are the basis for the recurring pattern of chemical behavior. The ground-state electron configuration has the lowest-energy distribution of the electrons. Atomic radius generally decreases from left to right across a period because the effective nuclear charge ____ while electrons are being added to the same outer level. These additional electrons are shielded _____ by inner electrons and are therefore attracted _____ strongly by the nucleus. The pauli ______ principle guarantees that no two electrons in the same atom have the same quantum number description. This means that the maximum number that can be accommodated by any orbital is ____.
