Give the electron configuration of nitrogen (See your text or a periodic table .) In the ammonium ion , the nitrogen atom has donated an electron . Would you expect the geometry of the ammonium ion (NH + ) to differ from the methane molecule? Why?
Beryllium trifluoride (BeF3-) is a "flat" molecule with the beryllium atom at its center. Sketch the molecule, showing the hybrid orbitals and the fluroide atoms. What hybrid orbitals would you expect to be present in BeF3?
