1800-102-2727Let’s hear an interesting story about Ununpentium, or the element with Atomic number – 115.
It was only in 2003, that ununpentium was artificially synthesised by scientists in a laboratory. But for more than decades, this element has been linked under a special connection with UFOs, aliens and other related phenomena! Thrilling isn't it! Let’s see how it goes.
This is in reference to a long-lived story of Bob Lazar, who in 1989 went public with what he claimed to be extremely confidential information about Element-115. Lazar claimed to be a former employee at Area 51, the hidden think tank of the Nevada Test and Training Range operated by the United States Air Force, where he was a reverse-engineering professional who studied crashed alien flying saucers. He claimed to have worked with element 115, which was used to pilot extraterrestrial spacecraft.
To quote him, " It was impossible to synthesise an element that heavy here on Earth. The substance has to come from a place where super-heavy elements could have been produced naturally,"
Lazar also claimed to have seen anti-gravity technology and nine alien spacecraft stored in a hangar at Area 51. When the great Dmitri Mendeleev organised the Periodic Table with around fifty nine element entries, he also kept thirty-three empty spaces for probable future elements. By 1939, all of Mendeleev’s boxes had been filled. But what he could never have imagined was that scientists would one day begin creating elements not found naturally.
Let’s find out more about this interesting element, that is not naturally available and is synthesised (at least on earth!) by humans.
TABLE OF CONTENTS
Ununpentium is an example of a laboratory-created synthetic element. It was first synthesised in 2003 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, by a joint team of Russian and American scientists. Due to its restricted manufacturing and availability, Ununpentium is only utilised in fundamental studies.
The Joint Working Party of international scientific bodies IUPAC and IUPAP recognised it as one of four new elements in December 2015. It was officially named “Moscovium’’ after the Moscow Oblast on November 28, 2016.
Moscovium (Mc) is a transuranium element with an atomic number of 115 in the modern periodic table that has been synthesised chemically. It is expected to be toxic, owing to its radioactivity and the likelihood that biological processes may displace other metals.
In August 2003, a joint team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, achieved the first successful synthesis of moscovium. The team was led by Russian nuclear physicist Yuri Oganessian that included scientists from Lawrence Livermore National Laboratory.
Moscovium is a highly radioactive element with a half-life of only 0.65 seconds for its most stable known isotope, Moscovium-290. It belongs to the seventh period of the periodic table and is classified as the heaviest pnictogen in group 15.
Moscovium should have properties similar to that of thallium as both these elements contain a very closely packed electron on the outside of a quasi-closed shell.

Uses
There is no biological use for it. As the metal is thought to be highly radioactive, it is believed to be extremely dangerous in nature.
Q 1. What is the IUPAC nomenclature of an element with the atomic number 115?
a. Ununpentium
b. Ununbium
c. Unnilbium
d. Unnilpentium
Answer: In the IUPAC nomenclature of elements with atomic number greater than 100, the code for 1 is un, for 5 is pent, and at the end, we add "ium". Therefore, when Z= 115, its IUPAC name is Ununpentium.
So, option A is the correct answer.
Q 2. The new name for Ununpentium, accepted by international bodies is?
a. Tenesium
b. Americium
c. Moscovium
d. Nihonium
Answer: Ununpentium was synthesised in Moscow in collaboration with Russian scientists. So, to honour that, it was named Moscovium.
So, option C) is the correct answer.
Q 3. To which period and group does Ununpentium belong?
a. Period 5, Group 17
b. Period 7, Group 15
c. Period 8, Group 7
d. Period 17, Group 18
Answer: The electronic configuration of Moscovium/Ununpentium is [Rn] 5f14 6d10 7s2 7p3. Hence, it belongs to period 7 and group 15.
So, option B) is the correct answer.
Q 1. What is Moscovium used for?
Answer: Only a few moscovium atoms have ever been created, and they are only used in scientific experiments. Nihonium is synthesised from it. Moscovium is a radioactive, synthetic substance about which little is known. It is known as a metal and is expected at room temperature to be solid. It rapidly decays into other elements, such as nihonium.
Q 2. Is Moscovium toxic?
Answer: The only known cause of moscovium is nuclear weapons. Moscovium has never been found in nature, and it has no biological function. It is expected to be poisonous, owing to its radioactivity and the likelihood that biochemical reactions will displace other metals.
Q 3. What is the 116th element?
Answer: Livermorium is a synthetic chemical element with the symbol Lv and an atomic number of 116. It is a highly radioactive element that was created in the laboratory and not found in nature.
Q 4. What is the most expensive metal on earth?
Answer: Palladium is the most expensive of the four main precious metals, with gold, silver, and platinum being the others. It is rarer than platinum, which is used in greater quantities in catalytic converters.
