Question

An element is recently discovered is placed in ${7^{th}}{\kern 1pt} {\kern 1pt} period{\kern 1pt} {\kern 1pt} and{\kern 1pt} {\kern 1pt} {10^{th}}$ group . IUPAC name of the element will be:
(A) Unnilseptium
(B) Ununnilium
(C) Ununbium
(D) Unununium

Answer 1

To answer this question, we first need to understand what IUPAC is. The International Union of Pure and Applied Chemistry (IUPAC) is a global federation of National Adhering Organizations that represents chemists from all over the world. The International Science Council has accepted it as a member.

Complete answer:
The high atomic numbers and systematic element names of new or yet-to-be-named elements on the periodic table make them immediately identifiable. The International Union of Pure and Applied Chemistry (IUPAC) utilizes an atomic number-based system, with all names ending in -ium. This employs both Latin and Greek number roots, each of which is denoted by a symbol. The scheme of numbers-root-symbols is as follows:
-nil n
-un u
-b(i) b
-tr(i) t
-quad q
-pent p
-hex h
-sept s
-oct o
-en(n) e
It's pretty arbitrary if your question was about official names rather than these placeholders. Copernicium (Cn) was given to element #112 (Ununbium or Uub) in honour of astronomer Nicolaus Copernicus. The procedure can be cumbersome, and the scientists can be picky.
There is a mechanism that aids in the identification of new found elements. Because the atomic number of the period in the seventh period and tenth group is a hundred and ten, it is placed in the seventh period and tenth group.
As a result, the name that should be given to the new element is ununnilium, which means un(1), nil (0)
So, the final answer is option (B) i.e., Ununnilium.

Note:
The number of protons in the nucleus of every atom of a chemical element is known as its atomic number or proton number. A chemical element's atomic number is the only way to identify it. It is the same as the nucleus' charge number.
