When an atom is bonded to other atoms, it can combine its valence shell orbital to form a new set of orbitals that is at a lower total energy in the presence of the other atoms than the pure atomic orbitals would be. This process is called hybridization, and the new orbitals that are formed are called hybrid orbitals. These hybrid orbitals can overlap with orbitals on other atoms to share electrons and form bonds. Such hybrid orbitals usually give...

13. In polyatomic atoms electrons fill the orbitals from the lowest energy to the highest. Write the electron configuration of oxygen. (If you don't remember what the electronic configuration is, look in the examples of the aufbau principle, above. If you don't remember the order of filling of the orbitals, see the “orbital filling diagram, above.) Answer 14. Now write the orbital diagram for oxygen: 226
