Meet the Four New Elements on the Periodic Table

IUPAC Announces the names of the elements 113, 115, 117, AND 118.

It’s time to meet the four new elements of the periodic table

At a somewhat record-breaking approval speed the IUPAC (the International Union for Pure and Applied Chemistry) has approved the four new elements names for the elements 113, 115, 117, and 118. Normally this process takes one to two years, but the IUPAC finished in five months because no changes needed to be made to the proposals. This means that ununtrium, ununpentium, ununseptium and ununoctium are no longer answers on Sporcle quizzes relating to the elements.

The elements that complete the seventh row of the periodic table are now formally named nihonium (Nh), moscovium (Mc), tennessine (Ts), and oganesson (Og) There are some new cool things because oganesson (O Ga Ne S S O N) can be spelled with element symbols, nihonium is named after Japan, and Mc is a new element symbol that is also a valid Roman numeral.

The update comes after a process where the public was invited to express their opinions on the four proposed names and their corresponding symbols. According to the IUPAC guidelines, an element can only be named after a mythological concept or character, a place or geographical region, a mineral, an elemental property or a scientist.

AND we might not be done as the exploration of new elements will continue. Scientists are still searching for elements beyond the seventh row of the periodic table and will be establishing a new joint working group to examine the criteria used to verify claims for the discovery of new elements.

Now that you are up to speed, let’s see how well you (now) know your elements per letter:
