The three formats are the old International Union of Pure and Applied Chemistry (IUPAC) table, the Chemical Abstract Service (CAS) table, and the new IUPAC table. The old IUPAC system labeled columns with Roman numerals followed by either the letter A or B. Columns 1 through 7 were ...
2, and 13–18; thetransition metalsin the columns labeled 3–12; andinner transition metalsin the two rows at the bottom of the table (the top-row elements are calledlanthanidesand the bottom-row elements areactinides; Figure 3). The elements can be subdivided...
Along the left side of the table, I labeled the rows alphabetically. (**This is optional but helps younger kids who are uncomfortable pronouncing the names of the elements yet.) They already have row numbers along the top. Laminating makes it re-usable! I used two file folders and hooked ...

There are seven rows (periods), 18 columns (groups), and four blocks in the periodic table. Groups are numbered from 1 (leftmost column) to 18 (rightmost column). The blocks are labeled the s-block, f-block, d-block, and p-block. The elements are also grouped into metals, metalloids...
I chose this sample to represent its element in myPhotographic Periodic Table Poster. The sample photograph includes text exactly as it appears in the poster, which you are encouraged to buy a copy of. Source:eBay seller hallmarkmetals
(fuzzy clouds), which is close as you can get to visualizing what an atom really looks like. The orbitals are labeled. It describes other ways to visualize atoms, namely, electron orbits (like planets) and surfaces of constant probability (bulgy blobs). It has a small periodic table ...
"Racket" may be the right word for this sample, which used to be a racquetball racket prominently labeled as "TITANIUM". If it were titanium, it wouldn't have melted at about 700C in my crucible of truth. It gets worse. It could have been one of many commonly used high-strength alum...
