All daughter isotopes (decay products) of element 117 were previously unknown; [73] therefore, their properties could not be used to confirm the claim of discovery. In 2011, when one of the decay products (289 115) was synthesized directly, its properties matched those measured in the claimed indirect synthesis from the decay of element 117. [74]
Tennessine (117 Ts) is the most-recently synthesized synthetic element, and much of the data is hypothetical. As for any synthetic element, a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes. The first (and so far only) isotopes to be synthesized were 293 Ts and 294 Ts in 2009.
Victor Ninov was born in Bulgaria in 1959. [4] He grew up in the capital city of Sofia. [5] In the 1970s, when Ninov was a teenager, he and his family left for West Germany; they bounced around from house to house. [6]

The periodic table could soon welcome a new element - it's currently unnamed but known as the super heavy element 117. You might want to sit down - it's time for a science lesson. "It's really ...
The scientists involved in the discovery of element 118, as well as those of 117 and 115, held a conference call on 23 March 2016 to decide their names. Element 118 was the last to be decided upon; after Oganessian was asked to leave the call, the remaining scientists unanimously decided to have the element "oganesson" after him.
Eventually, a deal was made, and Russia and the U.S. alternately got credit for and proposed a name for each element they discovered together or independently. So, element 105 was named dubnium ...
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
