1) Explain why atoms that are larger in size have lower ionization energies than smaller atoms ? 2) Suggest an element that would form the follwoing types of bonds with chlorine atom(element 17). If a particular type of bond is not possible for chlorine, state not possible and explain why. A) Polar Covelant bond b) Ionic Bond c) non-polar covalent bond d) metalic bond E) in the polar convaletn bond which atom, the chlorine or the element you suggested, would...

Much like the CO ligands, cyanide (CN-) ligands have IR stretching frequencies that are distinctive and therefore often particularly useful. Consult an appropriate character table, and give a reducible representation for the cyanide stretching vibrations in the square-planar tetracyanoplatinate(II) ion, Pt(CN)42-.

Task 3. Spectroscopy. a) Why are flouroscence bands lower in energy than absorption bands? b) If an electronic transition is symmetry forbidden and spin forbidden, list two ways of overcoming this to explain why the bands are still seen in the spectrum? c) Define the coupling operator that sits between the excited state wave function and the ground state wave function in the transition moment integral.
