Element Classes
Today you will be modifying your own periodic table, including information on the classes
of elements.
Objective: Students know how to use the periodic table to identify metals,
metalloids, nonmetals, halogens, noble gases, alkali metals, alkaline earth metals
and transition metals.
You will develop your own method of identifying each of the element groups or classes
above, and you will include a key (or legend) on your table to assist others in identifying
them as well.
1) Make a bold “staircase” to separate the metals from the nonmetals.
2) Color code the following groups (families)
Alkali metals
Alkaline earth metals
Halogens
Noble gases
3) Color code these element classes:
Transition metals
Metalloids, also called “Semi-metals” (B, Si Ge, As, Sb, Te, Po)
Non-metals (H, C, N, O, P, S, Se)
4) Complete the “color key in the upper left corner of your table
5) Identify each of the following areas of the table
“s-block”
“p-block”
“d-block”
“f-block”
6) Test Your Table
a) Compare your table with those produced by your class mates.
b) Attempt the “Element Classes” interactive review activity on my website,
using only your periodic table.
