A Brief Note about Plutonium by Glenn
Seaborg (20 sec)
One sentence on how Pu was a means of extending the boundary of the periodic
table.
Plutonium and Why It Was Kept a Secret
(2 min)
Glenn Seaborg talks about the discoveries of Actinium and Plutonium and the
reasons for keeping the discovery of Pu a secret.
The Prediction of the Actinide Series
by Glenn Seaborg (2 min, 19 sec)
Glenn Seaborg discusses the initial failure to chemically identify elements
95 and 96 (Americium and Curium) and later describes his prediction of the actinide
series.
Introduction from Bob Silva (1 min, 26
sec)
Bob Silva from the Lawrence Radiation Laboratory in Berkeley describes Glenn
Seaborg's prediction of an actinide series with elements 102 and 103 (Nobelium
and Lawrencium) discovered by this laboratory.
The HILAC or Heavy-Ion Layer Accelerator
(2 min, 16 sec)
The HILAC is shown and described. Experimental parameters for bombardment are
considered.
Discovery of Lawrencium (59 sec)
The presentation includes discussion of the discovery of Lawrencium with the
heavy-ion layer accelerator or HILAC and the reaction used to produce it.
How To Collect Lawrencium Atoms (1 min,
8 sec)
Bob Silva demonstrates and describes the experimental preparation for the collection
of Lr atoms.

The Discovery of Element 106-Finally
(38 sec)
Nuclear chemist Darleane Hoffman speaks on the confirmation of the original
discovery of element 106.
The Naming of Element 106 (19 sec)
A brief narration by Albert Ghiorso of the suggested name for element 106.
The Limits of Discovering the Heavy
Elements (18 sec)

a model of nuclear fission is shown.
What Good is a Heavy Element? (55 sec)
Narration by Albert Ghiorso. A chromatographic separation of Californium-249
is shown, with its subsequent placement on a platinum foil for bombardment.
