Note that each of these entries corresponds to one of the twelve periods respectively. Group six (R H superscript two, R 0 superscript three) contains the following information: (no entry for period 1), O = 16, S = 32, C r = 52, S o = 78, M o = 96, T o = 125, -, -, W = 184, -, U = 240. Group five (R H superscript two, R superscript two 0 superscript five) contains the following information: (no entry for period 1), N = 14, P = 31, V = 51, A s = 75, N b = 94, S b = 122, -, -, T a = 182, B l = 208,. Group four (RH superscript four, R0 superscript eight) contains the following information: (no entry for period 1), C = 12, B i = 28, T i = 48, - = 72, Z r = 90, S n = 118, ? C o = 140, ? L a = 180, P b = 207, T h = 231. Group three (-, R superscript one 0 superscript nine) contains the information: (no entry for period 1), B = 11, A l = 27, 8. Note the ach of these entries corresponds to one of the twelve periods respectively. The second group (-, R 0) contains the following information: (not entry for period 1) B o = 9, 4, M g = 24, C a = 40, Z n = 65, S r = 87, C d = 112, B a = 187, -, -, H g = 200,. Figure B shows the first periodic table developed by Mendeleev, which had eight groups and twelve periods. (credit a: modification of work by Serge Lachinov credit b: modification of work by “Den fjättrade ankan”/Wikimedia Commons) Figure A shows a photograph of Dimitri Mendeleev.

This periodic table in PDF format can be downloaded from here. This table also contains the element number, element symbol, element name and atomic weights of each element. This activity was featured on the following blog post: The Joy of Chemistry – A Unit in Photos a few years ago. This color periodic table contains the most common valence charges of the elements. If students have binders with a clear pocket on the outside front, I ask that they place it there for quick reference and access. I photocopy it double sided – one side stays blank while the other side is color coded.
