In summary, on November 28, 2016, the International Union of Pure and Applied Chemistry (IUPAC) announced the official names and symbols for four elements: nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og). These elements correspond to atomic numbers 113, 115, 117, and 118, respectively. This update fills the 7th row of the periodic table, with no elements yet discovered in the 8th row. Additional information and versions of the periodic table can be found on the websites of organizations such as NIST, Webelements, LANL, and the Royal Society.

An update of the periodic table from IUPAC is here.

The 7th row is full, but we have nothing from the 8th row so far.

https://www.webelements.com/tennessine/ (it had to end in 'ine' like the other halides). oakridgium wouldn't work.

FAQ: Official new names of superheavy elements

What are the criteria for officially naming a superheavy element?

The International Union of Pure and Applied Chemistry (IUPAC) has guidelines for naming new elements, including superheavy elements. These guidelines state that the element must be confirmed by multiple experiments and a discovery team must submit a proposal for the name.

How are superheavy elements named?

Superheavy elements are named using the IUPAC guidelines, which state that elements can be named after a mythological concept, a mineral, a place, a property of the element, or a scientist. The name must also end in -ium.

Why do superheavy elements have temporary names?

Superheavy elements are often synthesized in small amounts and can decay quickly, making it difficult to confirm their existence. Therefore, they are given temporary names based on their atomic number until they are officially named by the IUPAC.

How long does it take for a superheavy element to be officially named?

The process of officially naming a superheavy element can take several years. The discovery team must submit a proposal for the name, which is then reviewed by the IUPAC. If approved, the element will be given an official name and added to the periodic table.

Are there any superheavy elements that have not been officially named?

Yes, there are several superheavy elements that have been discovered but have not yet been officially named. These elements are given temporary names based on their atomic number until they are confirmed and named by the IUPAC.
