Chapter 1. Introduction and Review.
Glenn Seaborg has accomplished as enormous amount thorough out his life. Seaborg has had interactions with five separate presidents. He was also appointed Chancellor of the University of California at Berkley, Atomic Energy Commission, along with many more appointments, rewards, and discoveries.
Seaborg had donated his life to science. He contributed a numerous amount of information to the pool of information that we draw from. The world of science suffered a great loss when Glenn Seaborg died early in the year 1999.
In 1952 the H-bomb was detonated. Many new elements where found in the debris that was left over from the historic explosion. The elements that were discovered at that time later led to the discovery of many more elements, which were created by the bombardment of existing elements with Helium ions. These elements were discovered partly to the work of the well-known chemist Glenn T. Seaborg. These elements are now known as the transuranium elements. Each of these elements, while having many of the same characteristics, is unique in there own way. Such as plutonium (which occurs in nuclear fallout) gives off 22 million-kilowatt hours of heat energy per one kilogram! This element was also used in the Apollo missions to power equipment on the surface of the moon. Americium, the 95th element, is used in small amounts in smoke detectors. Curium, which is named for Pierre and Marie Curie, was used on the Mars Lander project, and also accumulates in bone marrow and causes damage to red blood cells. Californium, which has many uses, can be used in oil drilling, and the search for precious metals like gold and silver. Nobelium only has a half-life of 0.25 milliseconds!! Scientists believe that there will never be enough to even weigh due to its short life span. Other Transuranium elements include Berkelium, Einsteinium, Mendelevium, Fermium, and Seaborgium.
While many of these elements have few known uses with today's technology, it is important to know of them. These elements are uncharted waters and who knows what new uses will be found for them.
Question 1: Look at the electron configuration of the elements mentioned in the article. What atomic orbital in the configuration is not full?
A. 5f orbital is not filled.
Question 2: What is unique about the naming of Seaborgium?
A. Seaborgium was named while Seaborg was living.
Question 3: Take a look at Seaborg's history. What did Seaborg contribute to Mizzou?
A. He dedicated MU's research reactor.
Question 4: Do you believe man-made elements should be considered as elements and include them on the periodic table with other natural elements?
A. Open dicussion.
