IUPAC Nomenclature and Notation of Element -

IUPAC proposed a system for naming elements with Z > 100. By using these rules as follows.

  • The names are derived by using roots for the three digits in atomic number of the element and adding the ending-ium. The roots for the numbers are:

 

Digit

Name

Abbreviation

0

nil

n

1

un

u

2

bi

b

3

tri

t

4

quad

q

5

pent

p

6

hex

h

7

sept

s

8

oct

o

9

enn

e

 

  • In some cases the names are shortened; bi ium and tri ium are shortened to bium and trium respectively, and enn nil is shortened to ennil.

  • The symbol for the element is made from the first letters from the roots which make up the name. The strange mixture of Latin and Greek roots has been chosen to ensure that the symbols are all different.
