Question

Ds is the latest IUPAC approved name of the element of atomic number 110.
A.True
B.False

Answer 1

Darmstadtium is a chemical element. Its chemical symbol is Ds and atomic number is 110. GSI Helmholtz Centre firstly created Darmstadtium in the year 1994 for Heavy Ion Research near the city of Darmstadt in Germany, after which it was named. It is a d-block transactinide element in the periodic table.

Complete step by step answer:
Darmstadtium has no known biological role. A man-made element of which only a few atoms have ever been created. It is formed by fusing nickel and lead atoms in a heavy ion accelerator.
At the 42nd General Assembly in Ottawa, Canada, the IUPAC Council officially approved the name for elements of atomic number 110, to be known as darmstadtium, with symbol Ds.
So, it is True.

Therefore, the correct answer is option (A).

Note: Criteria and rules related to assigning priority of discovery of a new element were set up by the Trans fermium Working Group, TWG, in 199.At that time, elements up to element number 109 had been discovered. However, not all of them could be named because in some cases priority of discovery could not be clearly established. It was the task of the TWG jointly set-up by IUPAC and IUPAP to work out appropriate criteria and rules so that existing claims for discovery could be settled and that, for the future, the priority of discovery of new elements could be decided timely and unambiguously. New elements from 110 to 118 were synthesized since that time. Discovery of those elements was assigned using the criteria and rules set up in the 1991 TWG report, and all of the elements were named, from darmstadtium for element 110 to oganesson for element 118.
