Electron Orbital Diagram For Oxygen. Since 1s can only hold two electrons the next 2 electrons for o go in the 2s orbital. In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital.
The video uses kr as an example but the process is exactly as the same as what you need to do for oxygen. Since 1s can only hold two electrons the next 2 electrons for o go in the 2s orbital. The remaining four electrons will go in the 2p orbital.
Oxygen has 8 electrons and these are contained in 1s 2s and 2p orbitals.
Since 1s can only hold two electrons the next 2 electrons for o go in the 2s orbital. The remaining four electrons will go in the 2p orbital. Therefore the o electron configuration will be 1s 2 2s 2 2p 4. The 1s and 2s are fully occupied with two electrons each so they.
