How to Systematically Name Elements

Elements can be named using a systematic method based on their atomic number.

First, split up the atomic number into its individual digits. Then, for each digit in the atomic number, look up its systematic root:

DigitRoot
0nil
1un
2bi
3tri
4quad
5pent
6hex
7sept
8oct
9enn

Combine each of the roots and append "ium" to the end, finally applying any exceptions:

  • If bi or tri is followed by the ending ium (i.e. the last digit is 2 or 3), the result is '-bium' or -'trium', not '-biium' or '-triium'.
  • If enn is followed by nil (i.e. the sequence -90- occurs), the result is '-ennil-', not '-ennnil-'.

For example, element 123 would be un + bi + tri + ium, or unbitriium, which becomes unbitrium once the exceptions are applied.

Element Symbols

Notice that each of the roots begins with a different letter. To find the systematic symbol for the element, combine the first letter of each root for each digit and put them together. Finally, apply proper captitalization.

For example, element 123 would be [u]n + [b]i + [t]ri = ubt, or Ubt with proper element symbol capitalization.
