Electron Configuration of Oxygen. Its electronic configuration is [Ar] 3d 1 4s 2. For example, the electronic configuration of sulfur can be written as [Ne] 3s 2 3p 4, since Neon has an electronic configuration of 1s 2 2s 2 2p 6. The atomic number of oxygen is 8, implying that an oxygen atom holds 8 electrons. To add an extra electron to Ne, it would be necessary to begin a new shell that would be strongly shielded from the nuclear charge so the new electron would not be strongly attracted to the nucleus. Aufbau Principle • Electrons occupy orbitals of lower energy first. Explain why copper does not follow the expected pattern. Subshells: Energy levels of electrons are divided into subshells of equal energy orbitals. It turns out that the energy the electron configuration that is half-filled, 4s 1 3d 5, and filled orbital, 4s 1 3d 10, has lower energy than the typical filling order, 4s 2 3d 4, and 4s 2 3d 9.This pattern is followed in the 5 th row with Mo (#42) and Ag (#47).
