Test: Elements Nomenclature - JAMB MCQ

As per IuPAC nomenclature of periodic elements greater than 100, Un means 1, nil means 0 and oct means 8, so the element numbered 108 is unniloctium. It’s chemical names is Hassium and is represented by the symbol “Hs”. It is highly radioactive in nature and man made.

The element of Copernicium’s atomic number is 112. it is otherwise called as Ununbium as per the IUPAC nomenclature. The name Copernicium is given after the astronomer Nicolaus Copernicus. It’s a d-block transactinide element that belongs to Group-12.

As per IUPAC nomenclature, the roots are as follows: 0 – nil, 1 – un, 2 – bi, 3 – tri, 4 – quad, 5 – pent, 6 – hex, 7 – sept, 8 – oct and 9 – enn. So 115 is Ununpentium and the official name is Moscovium was named after the Moscow Oblast in which Joint Institute for Nuclear Research is situated.

As per IUPAC nomenclature, 0 – nil, 1 – un, 2 – bi, 3 – tri, 4 – quad, 5 – pent, 6 – hex, 7 – sept, 8 – oct and 9 – enn. Here it’s 109 so 1 – un, 0 – nil and 9 – enn, combining them its unnilennium (adding “-ium” after it).

Traditionally, IUPAC ratified the name selected by the discoverer. But later this led to the problem because the synthesis of these elements required costly equipment and laboratory as the elements with higher atomic numbers are highly unstable.

As per IUPAC nomenclature, the roots are as follows: 0 – nil, 1 – un, 2 – bi, 3 – tri, 4 – quad, 5 – pent, 6 – hex, 7 – sept, 8 – oct and 9 – enn. So the roots for 1, 1 and 9 are un, un, and enn. Hence the symbol of the elements is Uue.

Unnilhexium is the 106^th element as per IUPAC nomenclature, as the roots are un, nil, and hex which means 1, 0 and 6. The 106^th element’s official name is Seaborgium. Seaborgium is a synthetic element that is named after Glenn T. Seaborg.

Unnilquadium is a combination of un, nil, and quad i.e. 1, 0 and 4 as per IUPAC nomenclature. Its symbol is formed by joining the first letters. So combining u from uni, n from nil and q from quad, we get Unq.

As per the notations of the IUPAC nomenclature, the 101^st element is named as Unnilunium. When the Einstenium was bombarded with alpha particles, Mendelevium was discovered and named after Dmitri Mendeleev.

For claiming credit for discovering 104^th element, the Americans named it Rutherfordium and the Soviets named it Kurchatovium. While it’s named Unnilquadium as per IUPAC nomenclature. Neptunium is the 93^rd element.
