![]() 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. If you are looking with lots of last minute lessons on the periodic table, you’ve found an magazine which will help you. Height school and middle school students will appreciate the strategy behind the color encode. = 44, - = 68, ? Y t = 88, I n = 113, ? D I = 138, -, ? E r = 178, T l = 204, -. There are 7 lessons you canned teaching with color pencils and a blank periodic charts. 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. Elements on the periodic table can be grouped into families (vertical columns) based on their similar chemical properties. \): (a) Dimitri Mendeleev is widely credited with creating (b) the first periodic table of the elements.
