Great news for the science world! The International Union of Pure and Applied Chemistry has added four new elements to the periodic table.
The four new elements recently included in the periodic table of elements were discovered some time ago, but they were only received temporary names. As a results the former Ununoctium, Ununpentium, Ununseptium, Ununtrium, also known as elements 113, 115, 117, and 118, recently received names, honoring the person, county or country which discovered them.
Former UUT/113 is now called Nihonium. The element was discovered in Japan some time ago, and it seemed suitable to bear the name of its ‘place of birth’. Nihonium is a synthetic element, meaning that it is not naturally occurring. According to the team which discovered this element, Nh is extremely radioactive and highly volatile.
Nihonium has a half-life of approximately 20 seconds and compared to the other three elements which were recently included in the periodic table of elements, it’s the most stable.
The second element introduced in the periodic table of elements is Moscovium (Mc), formerly known as UUP/115. Moscovium was created by a team of Russian and American scientists back in 2003. The name stands as an homage to Russia’s capital city.
Occupying the 7th column in the period table of elements, Moscovium is a super-heavy and radioactive element. The element’s most stable isotope called moscovium-289 has a brief half-life (approximately 220 milliseconds).
The third element which was recently included in the period table is called Tennessine or Tn, for short. Formerly known as UUS/117, Tennessine was named after the state of Tennessee, where the element was developed. Tn’s ‘place of birth’ was the Oak Ridge National Laboratory.
Adorning the seventh column of Mendeleev’s table, Tennessine is a super-heavy element with a brief half-life estimated at 18 milliseconds. Like the other two super-heavy elements, Tn is very volatile.
The last element included in the periodic table of elements is called Oganesson. Formerly known as UUO/118, this element was named after Dr. Yuri Oganessian, the famous Russian nuclear physicist who discovered it.
Og is classified as being a transactinide chemical element (it’s a super-heavy element), belonging to the same family as Copernicium, Hassium, Dubnium, Nihonium, Moscovium, and Tennessine. Being a transactinide chemical element, Oganesson has a brief half-life, and it is highly unstable.
