The element with atomic number 108 is Hassium (Hs). Hassium is a synthetic element, and its discovery was confirmed in 1984 by a team of scientists in Darmstadt, Germany. It is named after the German state of Hesse, where the laboratory that discovered it is located. Hassium is a member of the transactinide elements, located in period 7 of the periodic table.
Hassium was first synthesized by bombarding lead with ions of iron. It is highly unstable and only produced in minute quantities. The symbol for Hassium is Hs, and it was officially accepted by the International Union of Pure and Applied Chemistry (IUPAC).
Thus, the correct answer is:
\[
\boxed{Hs}
