What type of element is 117?
transuranium element
Tennessine (Ts), artificially produced transuranium element of atomic number 117.
Is Oganesson noble gas?
First synthesized in 2002 at the Joint Institute for Nuclear Research in Russia, oganesson is the only element of group 18 of the periodic table (noble gases), which doesn’t naturally occur and must be synthesized in experiments.
Why is Oganesson a noble gas?
It’s also the heaviest element ever created and the only superheavy element (one whose atomic number exceeds 103) in the column of noble gases. Because of the large nuclear charge, inner-shell electrons orbit at near light speed, and their relativistic effects, notably spin–orbit coupling, are especially important.
How was element 117 created?
Scientists in Russia and the US have observed the fleeting existence of a new element with 117 protons, produced by firing calcium ions at a radioactive target. The Dubna discoveries were made by firing beams of the rare isotope calcium-48 at targets of heavy ions.

Why are the group 18 elements called noble gases?
Compounds of the Group 18 elements. The Group 18 elements have a particular name Noble gases. Noble gas is translated from the German noun Edelgas, first used in 1898 by Hugo Erdmann (1862 – 1910) to indicate their extremely low level of reactivity.
Which is the most numerous noble gas compound?
Xenon compounds are the most numerous of the noble gas compounds. Oxidation states of +2, +4, +6, and +8 with electronegative elements, e.g., XeF 2, XeF 4, XeF 6, XeO 4, and Na 4 XeO 6. Compounds of xenon bound to boron, hydrogen, bromine, iodine, beryllium, sulphur]
What are the three gases that boiled off after nitrogen?
After nitrogen, oxygen, and argon, the three gases that boiled off were krypton, xenon, and neon. Figure 11.1. 5: English chemist and founding director of the Indian Institute of Science, Morris William Travers (1872 – 1961).
