Seaborgium is a man made radioactive chemical element with the symbol Sg and the atomic number of 106. The most stable isotope is ²⁷¹Sg, which has a half-life of 2.4 minutes. In the past, it has been named eka-tungsten but is now named seaborgium.

What Seaborgium looks like is not known because not enough has been made to see it with human eyesight, but since it is in the same period as tungsten in the periodic table, its appearance and may be similar to it.

The element is named in honor of Glenn Seaborg.

Seaborgium is a transuranium element, which means that it is "beyond" (trans) the element Uranium in the sequence of elements.

Mendeleev predicted that Seaborgium would exist. He called the element eka-tungsten because of its location was near Tungsten in the Periodic Table.

Uses

Seaborgium has no uses at all because of how fast it destroys itself.

Chemistry

The chemistry of seaborgium is like the chemistry of tungsten. Seaborgium hexacarbonyl Sg(CO)₆ was made using the same method as tungsten hexacarbonyl and molybdenum hexacarbonyl. Its only known and studied as a gas.
