What is special about seaborgium?
Seaborgium (Sg) is an artificial chemical element with atomic number 106 and symbol Sg in the periodic table. It was discovered by Albert Ghiorso and named it after the Nuclear chemist Glenn T. Seaborg in the year 1974. It was the first element which is named after a person when he is alive.
What is seaborgium made of?
Source: Seaborgium is a synthetic, radioactive metal, created by nuclear bombardment. It has only been produced in tiny amounts. The metal is made by bombarding californium-249 with heavy oxygen ions. Isotopes: Seaborgium has 11 isotopes whose half-lives are known, with mass numbers from 258 to 271.
Why is seaborgium named after?
The name seaborgium was chosen to honor the man who shared the 1951 Nobel Prize in chemistry with former LBL Director Edwin McMillan for “their discoveries in the chemistry of the transuranium elements.” Born in 1912 in Ishpeming, Michigan, Seaborg received a Ph. D. in chemistry from UC Berkeley in 1937.

When was seaborgium made?
1974
Seaborgium was first produced by a team of scientists led by Albert Ghiorso working at the Lawrence Berkeley Laboratory in Berkeley, California, in 1974. They created seaborgium by bombarding atoms of californium-249 with ions of oxygen-18 using a machine called the Super-Heavy Ion Linear Accelerator.
What are 3 interesting facts about seaborgium?
Seaborgium Atomic Data Phase: It’s expected the seaborgium would be a solid metal around room temperature. Ionization Energies: Ionization energies are estimated. Isotopes: At least 14 isotopes of seaborgium are known. The longest-lived isotope is Sg-269, which has a half life of about 2.1 minutes.

What do you know about seaborgium?
Only small quantities of seaborgium have ever been synthesized, so there’s not a lot known about this element based on experimental data, but some properties may be predicted based on periodic table trends. Here’s a collection of facts about Sg, as well as a look at its interesting history.
How many isotopes of seaborgium are known?
Isotopes: At least 14 isotopes of seaborgium are known. The longest-lived isotope is Sg-269, which has a half life of about 2.1 minutes. The shortest-lived isotope is Sg-258, which has a half-life of 2.9 ms.
Is seaborgium similar to tungsten?
Experiments with seaborgium have shown it exhibits chemical properties similar to tungsten, its lighter homologue on the periodic table (i.e., located directly above it). It’s also chemically similar to molybdenum.
