Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 3

What’s the name of the 109th element as per the nomenclature?

Detailed Solution for Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 3

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).

Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 4

What’s the symbol of the element Unnilquadium?

Detailed Solution for Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 4

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.

Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 5

For the 115th element _________ is the name as per IUPAC nomenclature and __________ is the official name.

Detailed Solution for Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 5

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.

Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 6

What’s the atomic number of the element Copernicium?

Detailed Solution for Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 6

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.

Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 7

What are the roots of 1, 1, and 9 respectively as per the IUPAC nomenclature, and find out its symbol?

Detailed Solution for Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 7

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.

Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 8

What is the atomic number of the element unniloctium?

Detailed Solution for Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 8

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.

Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 9

14 elements after actinium is called        

Detailed Solution for Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 9

The correct answer to this question is option B, the 14 elements after actinium are called Actinides. Let us see what each of the options stands for to understand the answer in a better way.
First, let us see the series of elements lanthanides includes. Lanthanides are those elements which are in between atomic number 57 and 71. All the elements between atomic number 57 and 71 come under lanthanide series.
The series of lanthanides starts from element lanthanum which has the atomic number 57 and ends at the element lutetium which has the atomic number 71.
Second, actinides are those elements which are in between 89 and 103, starting from the element actinide which has the atomic number 89 and ending with the element lawrencium which has the atomic number 103.
Groups that come under atomic number 3 to 12 of the periodic table are called d-block elements. They are called d-block elements because d subshells are filled in the elements that come under d-block.
Groups that come under atomic number 13 to 18 of the periodic table are called p-block elements. They are called p-block elements because p subshells are filled in the elements that come under p-block.

Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 10

An element with atomic number will form a basic oxide________        

Detailed Solution for Test: Nomenclature of Elements with Atomic Numbers > 100 - Question 10

Sodium forms a basic oxide because it is a metal. Metals generally form basic oxides because they tend to donate electrons to oxygen atoms. In the case of sodium, when it reacts with oxygen, it forms sodium oxide, in which each sodium atom donates one electron to oxygen. This results in the formation of sodium ions (Na+) and oxide ions (O2-), which can combine to form the ionic compound sodium oxide. Sodium oxide is basic because it can react with water to form a solution of sodium hydroxide, a strong base.
