Selenide ion
Potassium nitrate
Sulfate ion
Iron(II) sulfate
Sulfuric acid
Iron(III) nitrate
Ammonia
Lead(IV) oxide
Ammonium ion

Assign the proper names to the following species, determine the oxidation numbers of elements
involved, compile their Lewis electron-dot formulas, identify & sketch the electron configuration
around their central atom & molecular geometry, determine if there are polar or non-polar, & if
polar – how the dipole is directed, estimate the valence (bond) angles. Apply resonance concept
where applicable.
