2. File:The Periodic Table of the Elements in Pictures.pdf

   en.wikipedia.org/wiki/File:The_Periodic_Table_of...

   English: This pictorial periodic table is colorful, boring, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical groupings.

3. Periodic table - Wikipedia

   Elements are placed in the periodic table according to their electron configurations, [38] the periodic recurrences of which explain the trends in properties across the periodic table. [39] An electron can be thought of as inhabiting an atomic orbital, which characterizes the probability it can be found in any particular region around the atom.

   Theodor Benfey's arrangement is an example of a continuous (spiral) table. First published in 1964, it explicitly showed the location of lanthanides and actinides.The elements form a two-dimensional spiral, starting from hydrogen, and folding their way around two peninsulas, the transition metals, and lanthanides and actinides.

5. Period (periodic table) - Wikipedia

   en.wikipedia.org/wiki/Period_(periodic_table)

   A period on the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, elements in the same group (column) have similar chemical and physical properties, reflecting the periodic law.

6. List of chemical elements - Wikipedia

   en.wikipedia.org/wiki/List_of_chemical_elements

   Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.

7. Periodic table (crystal structure) - Wikipedia

   The second table gives the most stable structure of each element at its melting point. (H, He, N, O, F, Ne, Cl, Ar, Kr, Xe, and Rn are gases at STP; Br and Hg are liquids at STP.) Note that helium does not have a melting point at atmospheric pressure, but it adopts a magnesium-type hexagonal close-packed structure under high pressure.

   One element is still missing an image: Rn. An image might exist out there, so if you track one of them (the images, not the element, unless of course you are qualified to be working with them), upload and insert it with a non-free use rationale. (But for Rn, make sure it actually visibly shows the element, or it'll probably get deleted.)
