Question

What is the IUPAC name of an element with atomic number 107.

Answer 1

Hint: Modern periodic table consists of more than 100 elements. All of them are named according to their discoveries. Elements having more than 100 atomic numbers are named through special nomenclature proposed by IUPAC.

Complete answer:
The modern periodic table is the collection of all the elements arranged according to their atomic numbers. While it was easy to name the elements with lower atomic numbers, through their discoveries and properties. The elements with atomic numbers higher than 100 were very rare, and were found in limited concentration, some of them are man-made. So, IUPAC proposed a method of nomenclature for elements with atomic numbers more than 100 to easily differentiate them through their respective atomic numbers.
This nomenclature was based on the atomic number assigned to each element. One respective name and symbol was given to all the numerals from 0 to 9. The elements with atomic numbers more than 100 were a combination of these names. The names assigned to numerals are,
0 – nil (n); 1-un (u); 2-bi (b); 3-tri (t); 4-quad (q); 5-pent (p); 6-hex (h); 7-hept/sept (s); 8-oct (o); 9-enm (e).
So, according to these names and symbols, element with atomic number 107 will be named as, 107 = un-nil-heptium (uns)
Hence, the name of the element with atomic number 107 is un nil heptium.

Note:
The need of nomenclature for elements with more than 100 atomic aroused when America and Russia claimed the element with atomic number 104, America named it rutherfordium (Rf), while Russia named it kurchatorium (Ku).
