|Periodic table showing the heavy elements as members of an actinide series. Glenn T. Seaborg formulated this arrangement in 1944 and it was first published in Chemical and Engineering News in December 1945.||Modern periodic table of the elements projected to element 118. Lanthanide (La) and actinide (Ac) series shown. With elements 106 (Sg), 107 (Ns), 108 (Hs), 109 (Mt), 110, 111, and 112 discovered.|
So here we are today. All the way up to the unnamed elements 110, 111, and 112. Seaborgium is under tungsten, it's an eka-tungsten. As I like to say, I'm looking forward . . . Darleane just showed me a copy of an article on the chemistry of seaborgium that they're just sending in. It has isotopes that are sufficiently long lived so one can do chemistry. I'm looking forward to the day when we're going to be talking about seaborgous and seaborgic and seaborgate ions. Finally, here is a periodic table to end periodic tables. Here I've gone beyond element 118 all the way on up to the next noble gas, it would be a noble liquid.
|Futuristic periodic table of the elements projected to element 168. With lanthanide (La), actinide (Ac) and superactinide series shown. With elements 106 (Sg), 107 (Ns), 108 (Hs), 109 (Mt), 110, 111 and 112 discovered.|
That brings me to the end of my talk. Thank you very much.
