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.
why do upper regions of an upright lung have a larger
ventilation-perfusion ratio and why lower regions of an upright
lung have a smaller ventilation-perfusion ratio
