Chemistry requires several types of Periodic Tables. Each one has a different purpose. You may want to begin with Mendeleev’s Periodic Table and a brief history. The Race to Invent the Periodic Table is only about five minutes. Mendeleev’s table was accepted because he left gaps for new elements—which were discovered in his lifetime. (It’s in the Cards is one of my favorite activities.) Below are a bunch of different types.
1. One early activity is to Color Code the Periodic Table. Here is a colorful version; however, I assigned specific colors to families of elements when the kiddos do the Periodic Table cards, a summer assignment. I like to be consistent to help them associate a group with a color, to remember the group.
2. I use a stack of blank copies which only the symbols for quizzes. My teens must memorize 1-50.
3. Additionally, I print copies with the names for quick reference.
4. Usually, the Periodic Chart of Ions is printed double-sided with a table with names and symbols.
5. When we do Periodic Trends, we use Electronegativities. Here is an interactive table with all sorts of I formation to use for trends: density, atomic radius, melting point, boiling point, and first ionization energy. (Here is a 3D Periodic Trend lab.) Ironically, the kiddos model their trend, including electronegativity on a plain Periodic Table.
6. IUPAC sets standards; here is the IUPAC Periodic Table.
7. I like Britannica’s PT with Roman numerals. Here is the explanation; the Roman numeral for the group represents the number of valence electrons, or number of electrons available for bonding. (Don’t confuse this with the Stock System, the Roman numerals used when the element forms differently charged ions with different oxidation states.)
On another note, I added a few transition elements to my card deck. For a few, I used Alchemical Symbols with their Latin names.
