![]() ![]() Systematic naming of Elements with Atomic Numbers Greater than 110 (PDF, 41 kB).As of 2006, ununoctium, element 118, is the highest element known. Note: These examples show conjectured elements. Therefore in practice, systematic names are just those with 3-letter symbols. The suffix -ium overrides traditional chemical suffix rules, thus 117 and 118 are ununseptium and ununoctium, not ununseptine and ununocton.Īll elements up to and including atomic number 111 have received permanent trivial names and symbols, so the use of systematic names and symbols is recommended only for elements 112 and above. The systematic symbol is formed by taking the first letter of each root, converting the first to a capital. The final ‘n’ of ‘enn’ is elided when it occurs before ‘nil’, and the final ‘i’ of ‘bi’ and of ‘tri’ when it occurs before ‘ium’. ![]() the sequence -90- occurs), the result is '-ennil-', not '-ennnil-'. 0 nil 1 un 2 bi 3 tri 4 quad 5 pent 6 hex 7 sept 8 oct 9 enn The roots are put together in the order of the digits which make up the atomic number and terminated by ‘ium’ to spell out the name. the last digit is 2 or 3), the result is '-bium' or -'trium', not '-biium' or '-triium'. If bi or tri is followed by the ending ium (i.e.There are two sandhi rules designed to prevent odd-looking names. Some of the roots are Latin and others are Greek the reason is to avoid two digits starting with the same letter. The roots are concatenated, and the name is completed with the ending -ium. Each digit is translated to a 'numerical root', according to the table to the right. The temporary names are derived systematically from the element's atomic number.
