Mоdule 2 Summаtive Assessment Questiоn: (35 pts) Describe the mоleculаr shаpe and polarity of the nitrate ion (NO3-): Write out electron configurations for each element in the ion. (5 pts) Draw orbital diagrams for each of the electron configurations you wrote to determine the number of unpaired electrons present for each element. (5 pts) Calculate the total number of valence electrons for the molecule/ion. (2.5 pts) Complete a Lewis structure for the molecule/ion showing ALL lone pair electrons, multiple bonds, and resonance structures, if necessary. (7.5 pts) Once your Lewis structure(s) is/are completed, determine and label formal charges for each atom. Hint: This can be used as a double-check that you did your Lewis structure(s) correctly. (5 pts) Dipole Moment: (5 pts) Draw bond dipoles (if present) Determine the overall dipole moment for the molecule (if present) Draw arrow pointing the correct direction next to your Lewis structure(s) (if present) Re-draw your Lewis structure as a 3D representation of the molecular shape, name the electron pair geometry and molecular geometry/shape of the molecule/ion. (5 pts) For Parts 4-7 do your best to describe your drawings in word form. I will create a separate spot that you can submit photos of your work for the whole exam so I can better distribute partial credit.
