International union pure applied chemistry

Answer 2

i)       The name of element is to be derived from atomic number. The following numerical roots are to be used.

ii)        The roots are together in the form of digits in the atomic number. They are terminated by the suffix 'ium'. If 'enn' occurs before 'nil', the second 'on' of 'enn' is dropped. Similarly the final 'i' of obi' and 'tri' is dropped when they occur before 'ium'.

iii)        The symbol of element is derived by composing the initial letters of the numerical roots (abbreviations) which constitute the name.
