Describe and explain physical properties of a number of representative
elements in terms of their atomic properties and position in the periodic
table. Use periodic relationships to predict certain properties of the
elements and their simple compounds (such as melting and boiling points).
Outline the methods that are used to produce Na, Mg, and Al.
Write chemical equations starting from a summary diagram as in
example 22-1.
Outline the series of reactions whereby rain water acquires temporary
hardness and how this hardness is removed by heating; write chemical equations
for reactions that can be used to soften temporary and permanent hard water.
Write equations to show the effect of H2O, of dilute and concentrated
HCL(aq), H2SO4(aq), and HNO3(aq),
and of NaOH(aq) on metals, such as those of
groups 1A and 2A, AL, Sn, Pb, Zn, Cd, and Hg.
Write equations to represent the amphoteric nature of the oxides and
hydroxides of Al, Sn, and Zn.
Cite examples of ways in which the first member of a group differs from
other members of the same family.
State some of the principal uses of the representative metals, and describe
some of the more important reactions (ones covered in lecture) and uses of
compounds of the representative elements.
Explain the origin of flame colors that are characteristic of some of the
elements.
