Back in January, officials had announced that a total of four fresh elements secured a spot permanently on the periodic table. These include elements 113, 115, 117 and 118 that fill up the 7th row on the periodic table. You might or might not be fascinated to know that they all had temporary names as well as symbols eg. Unseptium (Uus), Ununtrium (Uut), Ununoctium (Uuo) and Ununpentium (Uup). It seems like the debate over Uus is over and done with since these elements now have new names to go by.
Many Japanese, Russian and American researchers have claimed the discovery of these four elements. No wonder they were awarded the rights to name these elements. International Union of Pure and Applied Chemistry is an organization that confirms the discovery of new elements. The organization suggests that a new element has to be named after either of the following: a scientist, a place or geographical region, a mineral or similar substance, a mythological concept or character and a property of the element.
In light of that guidance, the proposed names are as follows:
- oganesson (symbol: Og and element with Z=118)
- tennessine (symbol: Ts and element with Z=117)
- moscovium (symbol: Mc and element with Z=115)
- nihonium (symbol: Nh and element with Z=113)
Nihonium comes from Nippon which is a Japanese term for Japan. Similarly, Moscovium is derived from the word, Moscow. Also, Tennessine has been named after the U.S. state of Tennessee which is renowned for its quality research in Chemistry. Interestingly, it now becomes the second state in the U.S. to appear on the periodic table. Finally, Oganesson refers to an 83 year old Russian physicist named Yuri Oganessian. Again, this marks the second time an element has been named after a living scientist.
The reason why these elements took so long to be discovered is that they are not found in nature, unlike aluminium and gold. These synthetic elements can only be made within a lab, soon after which they quickly decay. Research teams before these failed to have a proper look at the elements as they would morph into something else in no time. The Japanese research team are hopeful that it would soon discover element 119 in the near future.
