It's time to update your copy of the periodic table. Four new elements discovered in recent years have now been named, pending final approval by the international group of scientists in charge of the table.
The International Union of Pure and Applied Chemistry has announced these proposed names:
Nihonium and symbol Nh, for the element 113 Moscovium and symbol Mc, for the element 115 Tennessine and symbol Ts, for the element 117 Oganesson and symbol Og, for the element 118 The new superheavy, radioactive elements were actually added to the periodic table late last year and given these temporary and unremarkable names: ununtrium, ununpentium, ununseptium and ununoctoium.
An entry on the periodic table of the elements filled in and autographed by physics professors Joe Hamilton and A. V. Ramayya is displayed at Vanderbilt University in Nashville, Tenn. Their research team discovered a new element and named it tennessine after Tennessee.i An entry on the periodic table of the elements filled in and autographed by physics professors Joe Hamilton and A.

Mark Humphrey/AP But the IUPAC lets the discoverers of an element submit permanent names. Rules say they have to fall into one of five categories — a new element can be named after a mythological concept or character, a mineral or substance, a place or geographic region, a property of the element, or a scientist.
That's how we get nihonium, discovered by scientists at the RIKEN Nishina Center for Accelerator-Based Science in Japan. IUPAC says Nihon is one of two ways to say "Japan" in Japanese, and that element 113 is the first to have been discovered in an Asian country.
Moscovium was proposed by its discoverers at the Joint Institute for Nuclear Research in Dubna, which is near Moscow. Similarly, the name tennessine is a nod to scientific contributions from Tennessee, home to the Oak Ridge National Laboratory, Vanderbilt University and the University of Tennessee at Knoxville.
Oganesson was discovered by collaborating teams of Russians in the city of Dubna and Americans at Lawrence Livermore National Laboratory in California. The name honors Russian physicist Yuri Oganessian, a pioneer in the discovery of superheavy elements. He is the second person to have an element named after him while still alive. The first is Nobel-winning scientist Glenn Seaborg, who, among other things, discovered plutonium.
The new names are up for public comment for five months. Formal approval by the IUPAC Council will be announced in early November.
That means its too late for the more than 150,000 Change.org petitioners who wanted to honor the late Lemmy Kilmister of the heavy metal band Motorhead by naming element 115 "lemmium."
Tenessine. Sounds like as disease. Compound Francium Tennesside sound like a murder witness.
Boatymcboatfacium should be next.
"The periodic table should only contain elements that last an x amount of time, and that I learned about in my high school Chem class." LOLOL
“It is such a scam. They bring no value to world.”
I guess they bring no value to YOU.
Why do you presume to speak for the rest of the world?
These elements were only discovered within the last decade or so. It might be interesting to learn about some elements that were “useless” when they were discovered a couple of generations ago.
Related question: do smoke detectors also “bring no value to the world”?
Feynmanium and elements above the atomic number 137
Richard Feynman noted[7] that a simplistic interpretation of the relativistic Dirac equation runs into problems with electron orbitals at Z > 1/α ≈ 137 as described in the sections below, suggesting that neutral atoms cannot exist beyond untriseptium, and that a periodic table of elements based on electron orbitals therefore breaks down at this point. On the other hand, a more rigorous analysis calculates the limit to be Z ≈ 173.
Robert Lazar is fully vindicated, it seems.
Forget flash cards, you will remember the names better when they are set to music.

The point made was that the new elements do not exist in Nature, and hold together only for a short time. They may only have use in weapons as transitional states, with no other use. All of the elements you mentioned “hang around” long enough to be useful. A smoke detector that is viable for 1ms really isn’t of much use.
In particle physics, a millisecond is an eternity. If you're talking about planck time, you'd have a better argument. That said, even though these elements exist for very short periods of time, you can learn how they behave and interact and it helps verify the physics models.
Even further beyond that is that once it is known how these elements will behave, new interactions with other elements may become possible that creates something very desirable.
To reject the existence of these things because they only exist in an accelerator or only existed in the first few femtoseconds of the universe is silly and shortsighted.
Plutonium isn’t naturally occurring either. The difference between Boron and Carbon is a single proton, but the chemical properties are vast.
For now, these elements may only exist for milliseconds.
Who knows? Combine them in the right way and they may stick around.
It may also melt your face off, but don’t count science out because the process is messy. JJ Thompson discovered the electron. He also thought that because atoms are stable that electrons and protons existed in a sort of plum pudding, or a muffin-like thing where electrons and protons where sort of embedded together.
Wrong as hell on that account, but discovering the electron is why we love him.
Before Einstein proposed it, the idea of a bunch of north magnets all hanging out together closely packed together in the nucleus of an atom was absurd. That’s exactly what protons are, and what they do - happy to live very tightly packed in the nucleus. At the same time, electons (south magnets if you will) can only go two to an orbital.
One of these days all of this mishagas may lead to the graviton.
“Unobtainium”
In my world all kinds of things are made from that now, it used to be rare but is now very common. ALL new cars are made from it now.
“I’m waiting for 420 Doobium”
That would actually be Doobium 420 and you can make all you want with a few seeds and some dirt.
Paging Tom Lerner...
Why are they messing with the Periodic Table? Leave the table alone! First they kicked out Pluto, I did not say because I was not pluto.
And where is Rustoleum, you’d think that would be in there somewhere.
