Nomenclature – elements
The IUPAC proposed a system of naming elements with atomic number more than 100.
1) The names should be short and related to the atomic numbers of the elements.
2) The names are derived by using roots for the three digits in the atomic number of the element . The names should end in ‘ium’ whether the element was expected to be a metal or otherwise.
The roots for the numbers are-
0 -nil , 1 – un , 2 – bi , 3 – tri , 4 – quad , 5 – pent , 6 – hex , 7 – sept , 8- oct , 9 – enn.

3) The symbols for the elements is made up from the first letters from the roots which make up the name.
The names are written as a complete word in the examples a hyphen is inserted between each part of the name for clarity. They should be omitted.
