Periodic Table : New Elements

PROBABLE QUESTIONS ON NEW ELEMENTS IN THE PERIODIC TABLE 1)Whichthree (3) new elements are discovered recently and added to the Periodic Table in Chemistry? Ans: Darmstadtium (Ds),Roentgenium (Rg) and Copernicium (Cn). 2) What are the general nature of these new three elements? Ans: The elements are so large and unstable they can only be made in the lab and quickly break down into other elements. They fall in the type of ‘Transition Metals’. 3)Who discovered Darmstadtium ? Ans: by Peter Armbruster and Gottfried Münzenberg, under the direction of professor Sigurd Hofmann. It is originally called as "ununnilium" (one-one-zero for 110), 4) Who discovered Roentgenium ? Ans: It is originally called as "unununium" (one-one-one for 111) (in Latin language) 4) Who discovered Copernicium ? Ans : A team led by Sigurd Hofman . It is originally called as "ununbium" (one-one-two for 112). 5) These three elements are called as ? Ans : They are known as Super-heavy elements. 6) Which organisation should give recognition for new elements ? Ans: IUPAC 7)How Darmstadtium is made ? Ans: Four atoms of it were detected by a nuclear fusion reaction caused by bombarding a lead-208 target with nickel-62 ions: 8) Roentgenium is made from ? Ans : This new element had been created by bombarding bismuth with a beam of nickel atoms. 9)How Copernicium is made ? Ans: By smashing zinc and lead together 10) Nicolaus Copernicus suggested which fact in Physics? Ans: Nicolaus Copernicus is Prussian (old name of Germany) astronomer, who died in 1543. He is first scientist in Europe to suggested that the Earth revolves around the sun. 11) Roentegenium falls in which column in Periodic Table ? Ans: Element 111 falls in the same column of the periodic table as copper, silver and gold, so it is presumably a metal. 12) X-rays discovered by whom ? Ans : German physicist Wilhelm Rontgen is usually credited as the discoverer of X-rays because he was the first to systematically study them, though he is not the first to have observed their effects.
