Element 115 , also known as ununpentium (symbol Uup), is an element on the periodic table that has captured the imagination of scientists and science enthusiasts for its mysterious nature and potential applications in advanced technology. From its earliest mentions to the experiments that successfully produced it in the laboratory, element 115 has been the subject of fascination and speculation. But what do we really know about this strange element? In this article, we’ll explore everything we know about ununpentium, how it was discovered, its properties, and the theories surrounding this enigmatic element.
What is Element 115?
Element 115 is a superheavy element belonging to the family of synthetic elements on the periodic table. Superheavy elements are those with atomic numbers greater than 104 and are difficult to produce stably due to their short half-life. Ununpentium was first synthesized in the laboratory in 2003 by Russian and American scientists. Later, in 2015, it was given the name moscovium (Mc) in honor of the Moscow region, where the Joint Institute for Nuclear Research is located, the place of its discovery.
The Discovery of Element 115
The first successful attempt to synthesize Element 115 was carried out at the Joint Institute for Nuclear Research in Dubna, Russia, in collaboration with the Lawrence Livermore National Laboratory in the United States. To produce it, scientists bombarded atoms of americium (element 95) with ions of calcium (element 20). This process produced a few atoms of ununpentium, but these disintegrated within fractions of a second due to their instability.
This discovery was a major breakthrough in the research of superheavy elements and was subsequently confirmed by other experiments. In 2016, the element was officially recognized by the International Union of Pure and Applied Chemistry (IUPAC) , which approved its final name and symbol.
Properties of Element 115
Element 115 is highly unstable, meaning its atoms quickly decay into other elements. Because of its short half-life , it is very difficult to study in depth and only a few successful experiments have been performed. Here are some key facts about its properties:
- Atomic number : 115
- Chemical symbol : Mc (moscovium)
- Period in the periodic table : 7
- State : Metal, but it is extremely radioactive and disintegrates in milliseconds.
- Known isotopes : Several isotopes of moscovium have been created, the most stable being moscovium-290, which has a half-life of a few hundred milliseconds.
Scientists believe that moscovium lies in a region of the periodic table called an “island of stability,” in which the nuclei of certain superheavy elements may have longer lifetimes than expected. However, this stability is relative, as the half-lives of moscovium isotopes are still extremely short.
Theories and Speculations About Element 115
Aside from its scientific interest, Element 115 has been the source of various conspiracy theories and pseudoscientific speculation, especially in the context of extraterrestrial technology and advanced energy.
Bob Lazar and Element 115 One of the best-known aspects of ununpentium in popular culture comes from Bob Lazar , who claimed to have worked at a secret facility in the US’s Area 51. In the 1980s, Lazar stated that an unknown element (Element 115) was used in extraterrestrial technology, specifically anti-gravity propulsion systems. Lazar claimed that this element could produce incredibly powerful energy, which would have allowed UFOs to perform maneuvers impossible under the known laws of physics.
However, the scientific community rejects these claims, as there is no verifiable evidence of such applications. To date, no properties have been found that suggest that moscovium has extraordinary energy capabilities or that it can be used in propulsion systems.
What does the future hold for Element 115?
Although Element 115 has no practical applications at present due to its short half-life and the difficulty of producing it, its study remains fundamental to understanding superheavy elements and the structure of atomic nuclei. Scientists are particularly interested in exploring the “ island of stability ” in the periodic table, where superheavy elements with much more stable isotopes and potential technological applications are thought to exist.
Atomic properties of ununpentium, ELEMENT 115
The atomic mass of an element is determined by the total mass of neutrons and protons contained in a single atom belonging to that element.
The position in which Ununpentium is on the periodic table of elements is in group 15 and period 7.
It has an atomic mass of 288 amu (assumed) . The electron configuration of Ununpentium is [Rn] 5f14 6d10 7s27p3 (a guess based on bismuth). The electron configuration of elements determines how electrons are structured in the atoms of an element.
Bob Lazar is the first to talk about the chemical element with atomic number 115
Ununpentium, later added to the periodic table, If everything was a lie, how did he know about such an element?
Lazar has stated that the propulsion of the vehicle studied was powered by an antimatter reactor and was fueled by the chemical element with atomic number 115 (E115), which at the time was provisionally named ununpentium and had not yet been created artificially. (It was first synthesized in 2003 and later named moscovium.)
He said the propulsion system was based on a stable isotope of E115, which supposedly generates a gravity wave that allowed the vehicle to hover and soar .
No stable isotopes of moscovium have yet been synthesized . All have proven to be extremely radioactive, decaying within a few hundred milliseconds.

ELEMENT 115 “STELLAR FUEL” Ununpentium, Bob Lazar
Lazar said the craft had been dismantled and the reactor he studied was topped with a sphere or semisphere that emitted a force field capable of repelling human flesh.
He explained that the ship was divided into two main levels.
The reactor was placed in the centre of the upper level, with an antenna extending to the top, surrounded by three “ gravity amplifiers ”. These were connected to “ gravity emitters ” on the lower level, which could rotate 180 degrees to generate a “ gravity beam or anti-gravity wave ” and the craft would then travel “ belly first ” in this distortion field.
