A173592 Atomic numbers in the Mendeleyev-Moseley-Seaborg periodic table of elements read downwards columns, right to left.

Comments

A permutation of the natural numbers from 1 to 118.

The number of terms in the columns, also ordered right to left is: 7, 7, 6, 6, 6, 6, 6, 6, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2.

This is a consequence of finding 2*7=14, 6*6=36, 10*4=40, 14*2=28 elements with outer shells of s, p, d, and f-electrons.

Acronymic name: CMMSPT.

Example

The table contains 7 rows in 32 columns outlined as follows:
                                             1   2
                     3   4   5   6   7   8   9  10
                    11  12  13  14  15  16  17  18
      19  20....28  29  30  31  32  33  34  35  36
      37  38....46  47  48  49  50  51  52  53  54
55....69  70....78  79  80  81  82  83  84  85  86
87...101 102...110 111 112 113 114 115 116 117 118

Mathematica

elements = PadLeft[#, 32, 0] & /@ {{1, 2}, Range[3, 10], Range[11, 18], Range[19, 36], Range[37, 54], Range[55, 86], Range[87, 118]}; Transpose[elements] // Reverse // Flatten // Select[#, #!=0& ]& (* Jean-François Alcover, Oct 01 2012 *)
