What element has the longest electron configuration?
OganessonOganesson atoms have 118 electrons and the shell structure is 2.8.
What is the electron configuration of element 118?
Data ZoneClassification:Oganesson is a noble gasProtons:118Neutrons in most abundant isotope:176Electron shells:2, 8, 18, 32, 32, 18, 8Electron configuration:[Rn] 5f14 6d10 7s2 7p6 (presumed)6 more rows
Is there an element 119?
Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.
What is the heaviest element in the universe?
uraniumHeaviest Element in Terms of Atomic Weight Ununoctium is the heaviest element, but it is man-made. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289).
What is the most recently discovered element?
Their names are Nihonium, Moscovium and Tennessine. The fourth element is named Oganesson. It was named after a Russian nuclear physicist named Yuri Oganessian.
What can element 118 be used for?
Since only a few atoms of oganesson have ever been made, it has no practical uses outside of scientific study.
What is the heaviest element known to man?
uraniumThe heaviest element known to occur in nature is uranium, which contains only 92 protons, putting it 30 places below the putative new element in the periodic table. In the laboratory, physicists have managed to create elements up to 118, but they are all highly unstable.

What is the half life of element 118?
about 0.89 millisecondsOganesson’s most stable isotope, oganesson-294, has a half-life of about 0.89 milliseconds. It decays into livermorium-290 through alpha decay. On Novemer 28th, 2016, element 118 was named Oganesson with the symbol (Og).
Why is element 118 so expensive?
The most expensive natural element is francium, but it decays so quickly it can’t be collected to be sold. If you could buy it, you’d pay billions of dollars for 100 grams. The most expensive natural element that is stable enough to purchase is lutetium. … Atoms of synthetic elements cost millions of dollars to produce.
How long can super heavy elements live?
Previously known isotopes of lawrencium have fewer neutrons, and are less stable. This novel species, however, has an astonishingly long half-life of 11 hours, making it one of the longest-lived superheavy isotopes known to date. “Perhaps we are at the shore of the island of stability,” Dullmann says.
What is the rarest element?
element astatineA team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
What is the lightest element on earth?
HydrogenHydrogen is the lightest element and exhibits the simplest atomic structure. In addition, it is the most abundant element in the universe and can form bonds to nearly every element, such as s- and p-block elements.
What element has the highest atomic mass?
OganessonOganesson has the highest atomic number and highest atomic mass of all known elements.
Which is the lightest gas in the world?
HydrogenHydrogen is the lightest, most abundant and explosive gas on Earth. The atomic weight of Radon is 222 atomic mass units making it the heaviest known gas. It is 220 times heavier than the lightest gas, Hydrogen.
