Learning goals:
1. Be able to locate the following groupings on the periodic table: groups, periods, main group elements, transition
elements, inner-transition elements, alkali metals, alkaline earth metals, halogens, noble gases, metals,
metalloid, metals, lathanides, actinides, rare earth elements, transuranium elements.
2. Be familiar with both American labeling (IA, IIA, etc) and IUPAC labeling (1-18) of groups
3. Know the periodic trend for atomic size, being able to predict relative sizes of atoms
4. Know the periodic trend for metallic character, being able to predict relative metallic character of atoms
5. Be able to predict the values for physical properties of an element given information about other elements in the
same group
6. Be able to predict the formula for a compound containing a specific element if given a formula for a compound
containing an element in the same group
7. Sec. 6.6 covers writing electron configuration using the periodic table (we did this in Ch. 5). Will need to know
how to do this.
8. Predict the number of valence electrons for a specific main group element and draw its electron dot formula
9. Know the periodic trend for ionization energy, being able to predict relative abilities to lose electrons for specified
atoms
10. Be able to predict how many electrons are lost (or gained) by an atom, what is the resulting ionic charge, what is
the electron configuration for that ion, and be able to write the ion formula
11. Predict what noble gas an ion is isoelectronic with.
