Ununoctium is the last element so far. Over some years, scientists might synthesize an element by the name of ununnonium, or number 119.
Ununoctium is the last element on the Periodic Table. It's symbol is Uuo. It atomic weight is [294]. Its predicted phase is a solid.
The last element of each row is inert element. It is non-reactive and stable in nature.
A noblr gas
zirconium.
Hydrogen: represented on the table with by the symbol HIt has the lightest atomic weight of all elements at 1.00794Hydrogen is the most abundant chemical element, constituting roughly 75% of the universe's elemental mass.
seaborgium, the chemical element of atomic number 106, a very unstable element made by high-energy atomic collisions.
Krypton, and any other elements in the last column of the periodic table besides helium.
The last major changes to the periodic table resulted from Glenn Seaborg's work in the middle of the 20th Century. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements from 94 to 102. He reconfigured the periodic table by placing the actinide series below the lanthanide series. In 1951, Seaborg was awarded theNobel Prize in chemistry for his work. Element 106 has been named seaborgium (Sg) in his honor.Although Dmitri Mendeleev is often considered the "father" of the periodic table, the work of many scientists contributed to its present form.
The last element in each period is a noble element. It is non-reactive.
Argon (Ar, element number 18) is the last element in the third period of the periodic table.
Zirconium - Zr
zirconium.
Plutonium (atomic number 94) is the last element in the periodic table that may be found naturally, in trace amounts.
On the Periodic Table, a Period is one of the horizontal rows. If an element is last in it's period, then it's on the right hand side of the Periodic Table. There is an inert gas at the end of every Period.
element, last of the nobel gasses on the periodic table of elements
Helium.
The valency is 3+
The last member of alkali metals the Francium.
