Look at this diagram. Now think about hybridized sp2 orbitals. The above electron configuration is in the excited state, because one of electrons in the 2s orbital has promoted to the 2py orbital.1. Write the electron configuration of this atom in the ground state.
2. Which atom has this electron configuration?
3. Why this hybridized orbital called sp2?
4. Give an example of the molecule which has hybridized sp2 orbitals.
5. Apply your understanding of hybridization to another example, for orbitals sp.
6. Explain hybridized sp3 orbitals for ammonia and water.
7. Compare the molecular geometry of methane, ammonia, and water.
8. Explain the reason why methane, ammonia, and water have different molecular shapes, although have the same hybridized orbitals.
