The most recent additions to the periodic table were ununtrium (113), ununpentium (115), ununseptium (117) and ununoctium
They have atomic numbers 113, 115, 117 and 118 and were given temporary names of ununtrium, ununpentium, ununseptium and ununoctium
. You can read more about Element 117 here.
Consider the working names of the new elements: ununtrium, ununpentium, ununseptium and ununoctium
. All of them sound like the stuff the Resources Development Administration was mining in "Avatar." Permanent names are still to come.
IUPAC has now initiated the process of formalA[degrees] ising names and symbols for ununA[degrees] trium, (Uut or element 113), ununpentium (Uup, 115), ununsepA[degrees] tium (Uus, 117), and ununoctium
