Typical questions that can be answered based on learning in General Chemistry courses.
I. Using precise language to represent atomic and molecular entities (also called atomic and
Using accurate representational forms to distinguish between the following:
(a) bromide ion, molecular bromine, bromine atom
(b) ammonia, ammonium ion
(c) sodium ion, sodium
(d) molecular oxygen, oxygen atom
(e) hydrogen atom, molecular hydrogen, hydrogen cation (also called proton), hydrogen anion (also
called hydride ion)
II. Electron configurations and the relative stability of the closed shell electron configuration.
Write electron configurations for the monoatomic species in Part I, and identify which have closed
III. Lewis structures. Representing covalent bonds with lines, using "dots" (i.e., ":") for non-
bonding electrons and charge-separated ions for ionic bonds, draw Lewis structures for the
(a) ammonium bromide
