Classification of Elements & Periodicity in Properties Test 5

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.

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.

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).

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 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.

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 the roots for 1, 1 and 9 are un, un, and enn. Hence the symbol of the elements is Uue.

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.
